# 地震波作用下边坡稳定性的区域化时程分析Zonal Time History Analysis on Slope Stability under Seismic Excitation

Abstract:
This study discusses the propagation law of seismic wave propagating in the isotropic rock slope. In view of energy distribution, we can investigate the stability of slope carefully and comprehensively. But the computational cost is very high for analyzing the dynamic response of all the points of the whole slope based on the seismic wave theory. In order to reduce the difficulty, the rock slope can be divided into different region according to the propagation law of seismic wave; the displacement functions only for different regions are needed to be evaluated. The dangerous region and the potential sliding surface could be determined by the time-history analysis of displacement vector. The displacement response obtained by time-history analysis is consistent with the results observed from the experiment.
