Abstract

Abstract

The numerical model of Tangjiashan landslide is established to analyze its slope stability with Mohr-Coulomb theory and the strength reduction method. Firstly, the slope stability is simulated numerically under the natural state (only with the gravity action), and the calculated safety factor is 1.46, which indicates that the slope is relatively stable under the natural state. Secondly, Tangjiashan landslide stability is numerically simulated with large amplitude seismic wave of initial 30 seconds in Wenchuan earthquake, and calculates the free field boundary condition for the slope. The results show that the piercing plastic zone in slope is produced in Wenchuan earthquake, and the simulation plastic zone is good agreement with the real landslide slope body. Because of the earthquake acceleration, larger displacement and velocity of the slope appearing, which produce tremendous energy in the landslide and cause serious disaster and loss.
