Research the Layered Structure Affect on Seismic Dynamic Response of Rock Slope

Abstract

The deformation and failure induced by Wenchuan earthquake between bedding and anti-dip slope existence very big difference. The number and size of the bedding slope deformation and failure are much more than the anti-dip slope according to the investigation and analysis. In order to analyze the layered structure affect on seismic dynamic response of rock Slope. As bedding and anti-dip slope is the study object and the seismic dynamic responses of different layered structure slope have been studied by using ANSYS finite element method in this study. Analysis shows that slope as a structure, the internal structure different lead to the slope seismic dynamic response is also different. The bedding and anti-dip slope seismic dynamic response is discontinuous or mutations in the slope as layered structure interface the boundary. And the seismic dynamic stress, displacement and acceleration of the bedding slope are always greater than the anti-dip slope. The seismic response characteristics further increased the deformation and failure probability of bedding slope. The results consistent with the investigation conclusion that the stability of anti-dip better than the anti-dip slope
