Abstract:

"5.12" Wenchuan earthquake induced a large number of landslides, which had directly threaded human lives and property safety. But at the same time, it also provided valuable material to study the impact of earthquakes on the landslide. Taking Wangyuezhai landslide instantiated in Li city of Sichuan Province for example, on the basis of exhaustively mastering the basic characteristics of landslide before and after Wenchuan earthquake, stability and stress-strain features were then calculated and analyzed by limiting equilibrium method and finite difference method, which could analyze landslide’s deformation features from the respect of stress-strain. The analytical results are consistent with the macro-geological phenomena before and after the earthquake. These results provide a reliable basis for the future study of the impact of earthquakes on the landslide and geohazard prevention & geoenvironment protection.

Key words: Wenchuan earthquake, Wangyuezhai landslide, stability, limiting equilibrium method, finite difference method
