Surging News (www.thepaper.CN) previously reported incidents of plagiarism, allegations of plagiarism also includes Department level cadres.
Recently, China Academy of building research foundations, Dr Luo Pengfei, Deputy researcher to a surging news broke, which in April 2012, in a paper published in the journal of the construction technology in Zhangye city, Gansu province, suspected of being a pair of section-level cadres issued after the copy.
Then, surging news respectively from China know network and national digital library gets has above two article papers, a article for Luo Pengfei together with China building Science Institute tongjianxing, and Sun Xunhai, Zhejiang Province architectural design Institute Liu Jianfei, people co-authored of CFG pile composite Foundation detection frequently asked questions (following referred to "Luo Pengfei papers"); another a article for signature is Gansu province Zhangye city building management terminus Dragon construction of analysis China CFG pile composite Foundation in detection in the exists of problem (following referred to "Dragon construction papers").
Luo Pengfei papers
Long construction paper
Surging News showed that the similarity between these two papers text area height, conclusion, references are exactly the same.
From content Shang view, two article papers are is for CFG pile composite Foundation detection Shi, exists of load contains Board stiffness enough (load contains Board stiffness not arrived requirements), and mattress layer laying not reasonable, and maximum loaded pressure partial small, and low strain pile body integrity detection test points select not reasonable, and more pile type composite Foundation detection programme not reasonable, five big problem for respectively discussion analysis.
Analysis of the two papers mentioned above in the discussion of the first issue, Luo Pengfei paper uses baby entitled "load plate stiffness is not enough", long construction is using a "load plate stiffness did not reach the required", starting from the second sentence of the first paragraph of the section, opened the prelude of the two papers completely the same.
Luo Pengfei paper "load plate stiffness is not enough," wrote the first paragraph, "due to the design of CFG pile composite Foundation of pile spacing varied needs to detect sufficient rigidity of the load plate units available in different size, many test units for convenience, use a certain thickness of the steel plate in place. Some units feature a multi-layer steel plate, from the ground up geometry decreases combined load boards, as shown in Figure 1a. Beam combination plate, 4~5cm plate at the bottom, according to load size on the 1th floor on the rows of beams, 2nd layer two rows of beams, plates and jacks, as shown in Figure 1B. But many units with 1 layer of 4~5cm steel plate, two 2cm plates for load boards. "
Luo Pengfei paper "load plate stiffness is not enough," the first paragraph
Long construction paper "load plate stiffness did not reach the required" wrote the first paragraph, "for CFG pile composite Foundation to perform this test to be tested using different size, sufficient rigidity of the load plate to test the distance, but in the actual testing process of a certain thickness of the steel plate is used instead of situation is not uncommon. Some units feature a multi-layer steel plate, from the ground up geometry decreases combined load boards, as shown in Figure 1a. Beam combination plate, 4~5cm plate at the bottom, according to load size on the 1th floor on the rows of beams, 2nd layer two rows of beams, plates and jacks, as shown in Figure 1B. But many units with 1 layer of 4~5cm steel plate, two 2cm plates for load boards. "
Long construction paper "load plate stiffness did not reach the required" section first paragraph
Compared with those paragraphs, two papers only have difference in the language of the first sentence, starting from the second sentence of content are exactly the same.
Compare with Luo Pengfei papers, long construction paper only in the abstract, keywords, introduction (lead) and some other differences.
Judging from the time, Luo Pengfei papers in April 2012, the head of Ministry of housing and construction technology magazine 41st volume, published in issue No. 363; long construction paper published in October 2012, the Chinese General Chamber of Commerce Director of the theoretical research on the 28th issue of the journal of urban construction, 6 months later than Luo Pengfei papers.
On April 18, the Deputy Director of construction management in Zhangye City terminus Dragon build a surging news interview said, "I haven't seen before this paper was published (paper), when the published papers of the task to be completed, so on the premise of not seek personal advice published this paper using my name. "
Luo Pengfei also provided it with the dragon to the surging News-building message, soliciting messages show the long building had promised to withdraw.
In this regard, the Dragon explained that the construction, Luo Pengfei informed his papers after allegations of plagiarism, he had tried to contact their unit personnel to withdraw draft, because the agent had retired, the last withdrawn nothing definite about the draft.
Concluding remarks, references a verbatim
Surging news found, two article papers structure layout consistent, first is summary, and keywords part; next, Luo Pengfei papers is objective part, Dragon construction papers is lead part, two part content similar; then, two article papers are on CFG pile composite Foundation detection Shi exists of five big problem for respectively discussion; zhihou, two article papers are is through conclusion part on proposed of five big problem for analysis; last, two article papers are listed has six article reference literature.
Which, in on CFG pile composite Foundation detection Shi exists of five big problem for respectively discussion Shi, Luo Pengfei papers by mark of small title respectively is "load contains Board stiffness enough", and "mattress layer laying not reasonable", and "maximum loaded pressure partial small", and "low strain pile body integrity detection test points select not reasonable", and "more pile type composite Foundation detection programme not reasonable"; Dragon construction papers using of small title respectively is "load contains Board stiffness not reached requirements", and "mattress layer laying not reasonable", and "maximum loaded pressure partial small", and " Test point selection for low strain pile integrity testing is not reasonable "and" unreasonable detection scheme of multi-type-pile composite Foundation ".
The five headings comparison, two papers only in discussions about the load plate stiffness at the first subheading is slightly different.
Surging news found, stiffness is also from the discussion on load part of the beginning of the second sentence of the first paragraph, two papers on text content, text illustrations, punctuation and so on are almost exactly the same.
For example, Luo Pengfei papers in the second paragraph of part on the load plate stiffness writes, "for example, a project for ground treatment of high-rise building using CFG pile composite Foundation programme, design requirements for bearing capacity of composite Foundation 400kPa, square pile, pile spacing is 1.5M. 1th detection unit with 1.5mx1.5M, 4~5cm steel plate as the load plate, put Jack done static loading test on the load plate, as shown in Figure 1c. During the experiment, along with the increased load, load plate significantly depressed around the upturned flexural deformation in the middle. Test results of composite Foundation bearing capacity characteristic value does not meet the design requirements. Units of other units, the project detection, load Board has sufficient rigidity, the test results meets the design requirements of characteristic value of bearing capacity of composite Foundation 400kPa. "
Long construction paper in the second paragraph of part on the load plate stiffness, "for example, a project for ground treatment of high-rise building using CFG pile composite Foundation programme, design requirements for bearing capacity of composite Foundation 400kPa, square pile, pile spacing is 1.5M. 1th detection unit with 1.5mx1.5M, 4~5cm steel plate as the load plate, put Jack done static loading test on the load plate, as shown in Figure 1c. During the experiment, along with the increased load, load plate significantly depressed around the upturned flexural deformation in the middle. Test results of composite Foundation bearing capacity characteristic value does not meet the design requirements. Units of other units, the project detection, load Board has sufficient rigidity, the test results meets the design requirements of characteristic value of bearing capacity of composite Foundation 400kPa. "
Even the punctuation marks are those paragraphs are exactly the same.
In the subsequent "cushion paved is not reasonable," "maximum loading pressure is too low", "low strain pile integrity test point selection is not reasonable" and "unreasonable detection scheme of multi-type-pile composite Foundation" section, two essays are almost exactly the same.
For example, Luo Pengfei thesis "laying of cushion unreasonable" section in the first paragraph of says, "General requirements according to design requirements dug a test pit, flat-size and load the same pits, depth and thickness of cushion, as shown in Figure 2a. According to the design requirements of ramming paving cushion filling, thickness of 150mm. Ensure undisturbed soil lateral constraints on the cushion. Install load plate and load after close contact with the cushion. "
Long construction paper "laying of cushion unreasonable" for part of the first paragraph, "General requirements according to design requirements dug a test pit, flat-size and load the same pits, depth and thickness of cushion, as shown in Figure 2a. According to the design requirements of ramming paving cushion filling, thickness of 150mm. Ensure undisturbed soil lateral constraints on the cushion. Install load plate and load after close contact with the cushion. "
These two sections are exactly the same punctuation.
Surging news closer inspection found that compared with Luo Pengfei papers, two long construction paper omitted data with formulas of calculation process. The two appear in the "maximum loading pressure is too small" portion of the second and third paragraphs.
For example, Luo Pengfei thesis "maximum loading pressure is too small" third paragraph of section wrote, "If the maximum loading pressure increases, such as the selection of characteristic value of bearing capacity of composite Foundation of the design requirements of 2.1 times, namely 420kPa, 3 static loading test and 1/2 maximum load bearing capacity by pressure control, results are as follows: f1=210kPa;f2=210kPa;f3=180kPa. Average 200kPa, very poor 30kPa, very poor and the average ratio of 15% ≤ 30%, the bearing capacity characteristic value is
To meet the design requirements. "
Luo Pengfei thesis "maximum loading pressure is too low," the third paragraph of part
Long construction paper "the maximum loading pressure is too small" part of the third paragraph is, "If the maximum loading pressure increases, such as the selection of characteristic value of bearing capacity of composite Foundation of the design requirements of 2.1 times, namely 420kPa, 3 static loading test and 1/2 maximum load bearing capacity by pressure control, results are as follows: f1=210kPa;f2=210kPa;f3=180kPa. Average 200kPa, very poor 30kPa, very poor and the average ratio of 15% ≤ 30%, the bearing capacity characteristic value is: fspk=200kPa to meet the design requirements. "
Long construction paper "the maximum loading pressure is too low," the third paragraph of part
Long construction paper at the time of calculation of characteristic value of bearing capacity fspk calculation is omitted.
In addition, two papers in the concluding remarks, references section is verbatim.
Luo Pengfei thesis and conclusion as "bearing capacity of CFG pile compound Foundation should be determined by field loading test of composite Foundation and composite Foundation with both in the design phase and in the acceptance stage, loading test of composite Foundation with the reliability of the results is critical. Aiming at detecting problems that occur, it is recommended that should ensure the following. 1) loading plate shall have sufficient rigidity, to reflect shared responsibility between pile and soil of composite Foundation load characteristics. 2) cushions laid to simulate the behavior of actual project, level of cushion to have a role in lateral force. 3) maximum pressure should be due more than twice times the design pressure. 4) low strain test point selection in addition to the note should be evenly distributed on the plane, but also note that random point in order to guarantee the authenticity of defective piles and statistics. 5) should adopt four of multi-type-pile composite Foundation pile detection scheme, the pile of this article should use square load plate, two main and two auxiliary piles which are located in two on the diagonal. "
Long construction paper's conclusion is that "bearing capacity of CFG pile compound Foundation should be determined by field loading test of composite Foundation and composite Foundation with both in the design phase and in the acceptance stage, loading test of composite Foundation with the reliability of the results is critical. Aiming at detecting problems that occur, it is recommended that should ensure the following. 1) loading plate shall have sufficient rigidity, to reflect shared responsibility between pile and soil of composite Foundation load characteristics. 2) cushions laid to simulate the behavior of actual project, level of cushion to have a role in lateral force. 3) maximum pressure should be due more than twice times the design pressure. 4) low strain test point selection in addition to the note should be evenly distributed on the plane, but also note that random point in order to guarantee the authenticity of defective piles and statistics. 5) should adopt four of multi-type-pile composite Foundation pile detection scheme, the pile of this article should use square load plate, two main and two auxiliary piles which are located in two on the diagonal. "
These two papers conclusion part is likewise even the punctuation marks are exactly the same. Meanwhile, two papers listed the same six references.
Luo Pengfei references in the papers
Long construction paper references
Title, keywords, introduction (introduction), part of the same
Where the difference of the two papers appeared in titles, abstracts, keywords and other parts, but these parts also have varying degrees of similarity.
For example, the two papers are testing frequently asked questions analysis of CFG pile composite Foundation, Luo Pengfei thesis is entitled of the composite Foundation with CFG pile inspection frequently asked questions, long title of construction paper for the analysis of problems existing in CFG pile composite Foundation in detection.
Similarly, the two papers of the keywords is not exactly the same, but the ratio is high.
Luo Pengfei thesis keyword is "Foundation; CFG pile of multi-type-pile composite Foundation; static load tests; low strain dynamic test."
Luo Pengfei thesis title, abstract, keywords
Long construction paper keywords is simple, namely "CFG pile foundation construction static load test".
Construction of long article titles, abstracts, keywords A businessman said the bribery involved in Gansu
In addition, two papers in the introduction (lead) though vary greatly, but there are similarities.
Luo Pengfei paper writes in the foreword, "according to the technical specifications of ground treatment of buildings JGJ79-2002 (hereinafter referred to as the code), after construction of CFG pile composite Foundation required for composite Foundation bearing capacity and pile integrity testing. Under normal circumstances, the actual construction of single piles or pile loading test to determine the bearing capacity of composite Foundation with low strain dynamic testing of pile integrity. Found in the actual project implementation is not good enough for test of composite Foundation in some places, some quite serious, which affects the ability to make a correct evaluation of construction and acceptance. This paper discusses some of the common problems encountered. "
Luo Pengfei preface
Long construction paper writes in the introduction, "in order to better ensure the quality of CFG pile composite Foundation to meet the design and construction standards, according to the technical specifications of building Foundation treatment of JGJ79-2002 (hereinafter referred to as the code) request, upon completion of the Foundation, should carry out necessary composite Foundation bearing capacity and pile integrity testing. However, due to testing process during the actual process is not standard, and of research results for the Foundation construction quality is ready to evaluate performance, serious impact on the quality and safety of the construction works as a whole. Following this detailed explanation in the article. "
Long construction paper introduction
Those paragraphs not only refer to the "technical specifications of the building Foundation treatment", contents and structure are very similar, both point out that "the composite Foundation bearing capacity and pile integrity testing" the necessity of, and pointed out that problems in the process, finally the article content, that is, for bearing capacity of composite Foundation and pile integrity testing problems in the process of discussion and analysis.
"The agent retired, nothing about the withdrawn draft"
Luo Pengfei surging told the news, he is Wanfang data library to find relevant literature, found parts of the long construction paper and one of his papers is the same.
Luo Pengfei said, he wrote a long-building I, unit, and Gansu province, discipline Inspection Commission, Gansu Provincial Department of construction in Zhangye city, Gansu province, discipline Inspection Committee and discipline Inspection Commission, Dragon build has reply message.
Construction of long promised to be withdrawn as soon as possible in the message draft.
Today, the long construction paper are still available on the open platform is available for download.
In this regard, the long construction explained that, prior to the publication, he did not know about plagiarism, published papers and personal no matter when its units in order to complete the tasks in published papers, published using his own name. Luo Pengfei informed his papers after allegations of plagiarism, he had tried to contact the relevant personnel to withdraw draft, but because the person in charge has retired, the last withdrawn draft also disappear.
