Study on the Stability Influence Factors of Bedding Slope under the Action of Seismic Load

Abstract

Taking Magunyan landslide located in Beichuan County as a typical example, the stability influence factors of bedding slopes under the action of seismic load were analyze by using the ANSYS software in this study. The influence factors include excavation, interlayer cohesion and friction coefficient, earthquake magnitude and vibration direction. The related analysis showed that significant influences of excavation existed on the deformation and failure of slopes. And the bedding slopes stability increasing with the interlayer cohesive, the interlayer friction coefficient and earthquake magnitude increases. The analysis also showed that horizontal vibration is the most detrimental on the stability of slopes.
