Abstract

Abstract

The magnifying coefficient of earthquake acceleration peak value could be obtained,using numeric calculation method to analyze the earthquake response and compare inner points with ground reference ones in earthquake for a certain slope model．The most dangerous stress state of the slope could be obtained,using numeric calculation to multiply the acceleration magnifying coefficient by ground designed acceleration as the level acceleration of a point．In order to estimate the earthquake dynamic stability of a slope,the potential sliding faces were enacted and their safety factors were analyzed．
- slope,
- earthquake response,
- dynamic stability
