Finite element analysis of Jiangkou reservoir-induced earthquake

Qi Wenhao~(1),Bo Jingshan~(1,2),Li Zhende~3(1.Institue of Engineering Mechanics,China Earthquake Administration,Harbin 150080,China;2.Institute of Disaster-Prevention Science and Technology,Beijing 101601,China;3.University of Naval Engineering,Tianjin 300450,China)  
An earthquake in Wulong possibly induced by Jiangkou reservoir impounding is analyzed by using finite element method.When the Jiangkou reservoir is analyzed,its different breadth cases and a zone of fracture going through its bottom are considered,and the maximal shear stress in the reservoir bottom rock is shown.The analysis results are as follows: it is very possible that the reservoir bottom rock will be destroyed,the reservoir-induced earthquake is likely to be induced,and the greatest earthquake magnitude is about 5.
