Dynamic Stability Analysis of ~#2 Block in Left Bank of Baihetan Project

Yun Qian

Abstract

This paper discusses the characteristics of slope dynamic stability analysis method,which is often studied by pseudo-static method,time history analysis method and strength reduction method.Taking #2 block in left bank of Baihetan project in Jingsha River basin for an example,the limit equilibrium method of rigid body and FLAC3D software are used to analyze the stability under the seismic loading.At the same time,the dynamic stability safety factor is calculated with pseudo static method,time history analysis method and strength reduction method.Finally,the dynamic stability of the block is evaluated synthetically.
