 It is also said that the Three Gorges dam is deformed? Expert: pure malicious speculation

Huang Xiaokun, a researcher at the Chinese Academy of Building Sciences, received many inquiries these two days. The reason is that there is a picture of him posted on the reported microblog.

The top of the picture is a screenshot of a friends circle from unknown sources, with the words Mr. Huang Xiaokun, Ningde, Fujian Province and his comments; the bottom is a screenshot of the introduction materials of researcher Huang Xiaokun of China Academy of Building Sciences. This composite picture will make people think that Huang Xiaokun in the two screenshots is the same person.

The screenshot of that circle of friends has nothing to do with me, and I dont know who the Mr. Huang Xiaokun of Ningde, Fujian is, or why my personal information was posted. Huang Xiaokun told SciTech daily.

Huang Xiaokun was shocked when he first learned the news from his friends. My scientific research work is mainly related to housing construction, has no direct relationship with water conservancy and hydropower projects such as the Three Gorges Dam, and has not made any comments related to the Three Gorges dam. Huang Xiaokun said.

The monitoring shows that the operation of the Three Gorges project is safe and reliable

In fact, its not the first time that rumors of Three Gorges dam deformation have emerged. In July last year, experts have been trying to understand the rumors and pictures of the so-called distorted dam on social media. Unexpectedly, a year later, this old stem was turned over again for speculation.

In this regard, Zhang believes that it is necessary to popularize relevant common sense again to avoid misleading the public and confusing the public with false rumors.

At the same time, in order to comprehensively, accurately and timely grasp the working behavior and safety status of the buildings in the Three Gorges project, a large number of safety monitoring facilities with complete categories are arranged in the Three Gorges project area, with a total of 3 categories, 14 subjects and 12087 monitoring instruments, to conduct automatic real-time monitoring and analysis of the working behavior of the project.

The monitoring data since the water retaining operation of the Three Gorges dam show that the buildings work normally and the operation of the project is safe and reliable. Wang Xiaomao said that in terms of dam deformation, the settlement difference between adjacent dam sections is within 2mm, and there is no uneven settlement of the dam body; the horizontal displacement of the dam foundation changes very little, and the dam foundation is stable within the monitoring error range; the maximum horizontal displacement from the dam crest to the downstream is 30mm, which conforms to the deformation law of the existing concrete gravity dam at home and abroad, and each index is within the design allowable range.

Under the action of pressure load, general buildings will produce certain displacement, which is a normal phenomenon in accordance with the law. Zhang boting believes that as a very large building, under the action of huge water pressure, the maximum horizontal displacement of the dam crest to the downstream is not more than 30mm, which shows that the dam structure stability is very high.

From the first impoundment in October 2010 to 175 meters, the Three Gorges project has achieved the goal of 175 meters impoundment for 10 consecutive years, and has achieved remarkable comprehensive benefits in flood control, power generation, shipping and water resource utilization.

The flood control capacity of the Three Gorges project is 22.15 billion cubic meters. Through the joint operation with the upper reservoir group, the flood control pressure in the middle and lower reaches of the Yangtze River can be effectively relieved and the great flood control effect can be played. Wang Xiaomao, for example, said that in July 2012, there was a major flood in the Yangtze River Basin. Since the establishment of the Three Gorges reservoir, the maximum inflow peak has reached 71200 m3 / s, the maximum peak reduction has reached 28200 m3 / s, and the peak reduction is nearly 40%, greatly reducing the flood control pressure in the middle and lower reaches of the Yangtze River. According to statistics, by the end of 2019, the Three Gorges reservoir has accumulated 51 times of flood detention, with a total storage capacity of 160.118 billion cubic meters, playing an important role in flood control and disaster reduction in the middle and lower reaches of the Yangtze River.
