工程科学（英文版） 2007年第2期5卷 115-123页

作者： Li Ping~1, Li Yuanjun~2, Yang Mei’e~1(1.Institute of Geology, china Earthquake Administration, Beijing 100029, china 2.college of civil Construction engineering, Wuhan university, Wuhan 430072, china)

The Three-Gorge water conservancy Project on the Yangtze River started to impound water by locking gates on June 1, 2003. A swarm of more than 2000 small earthquakes suddenly occurred densely along the river section in Xinling Town north of Badong, Hubei Province, on June 7. This caused grave concern in the following years, but, with the completion of the second- and third-phase engineering construction, the water level in the reservoir will rise up to 156 m and 175 m respectively, no matter whether it can induce larger and stronger earthquakes. After an analysis of the distribution of active faults in the eastern part of the reservoir area, their intersections and capability to generate earthquakes from a seismo-tectonic viewpoint, we consider that after the reservoir impounding, two potential focal zones existing in Badong and Zigui counties may generate M 5.5 earthquake, the seismic intensity of which may reach Ⅷ. It will induce landslide bodies in the reservoir area to be reactivated and slide. The evidence is the large-scale landslide occurring on the Shazhenxi Creek river in Zigui County on June 12, 2003.

Characterizing the Infiltration Process in Low-permeable Bedrock by High-density Electrical Resistivity Tomography

16th IAHR-APD Congress and 3rd Symposium of IAHR-ISHS

作者： Xinyong Xu,Zhenyue Ma,Zhiqiang Song,Baoyou Zhao②,Wei Xu③ ② School of civil and Hydraulic Eng.,Dalian university of Technology,china ③ college of water Resourse Shenyang agricultural university,china

Based on the construction simulation project model,this paper realizes the simulated construction with keeping constant internal pressure of the spiral case in hydropower station through the nonlinear FEM calculation and taking the contact property between the spiral case and concrete into consideration. In this article,it researches the contact state of the spiral case and the peripheral reinforced concrete in the structure of the hydraulic turbine,gives the initial crack opening value,and then makes an analysis on the stress and characteristic of the spiral case and reinforcement on the process and the development of the concrete stress. The conclusion shows that pouring concrete programme under the head of keeping constant internal pressure is reasonable and offers a certain value to the spiral case construction and long-term operation evaluation.

基于ANSYS的钢筋混凝土结构三维实体建模技术探讨

2011 International Symposium on water Resource and Environmental Protection(ISWREP 2011)

作者： Gang Wang Jie Dong Yanfang Diao college of water conservancy & civil engineering Shandong Agriculture university Tai’an 271000 china Qiyou Zhou Shiyan Wu Department of Earth Sciences & engineering Nanjing university Nanjing 210093 china

The geophysical imaging technology of high-density electrical resistivity tomography （ERT） was tested to characterize the infiltration process in low-permeable bedrock in-situ. The distributional pattern of the bedrock resistivity images obtained during the infiltration at different times by ERT clearly illustrates the properties of infiltration process and the characters of percolation in the low-permeable bedrock. This indicates that it is feasible to characterize the three -dimensional infiltration process happened in bedrock by ERT and the application prospect that acquiring the parameters of the low- permeable media is profound.

关键词： infiltration process low-permeable bedrock electrical resistivity tomography ERT.
