Stability Analysis of Slope Under Rainfall Infiltration and Optimal Design of Anti-slide Pile

Abstract

Based on practical slope engineering, analysis model of seepage-stress coupling under continuous rainfall condition was established by Geo-Studio (geotechnical analysis software). The dynamic change process of slope safety factors with time was analyzed. The results show that in the same Infiltration, slope under small intensity but long duration rainfall has lower safety factor and higher risk. In this unfavorable condition, analyzed and optimized the retaining structure of the antislide piles, and puts forward the optimization of landslide treatment scheme and the rainfall instability threshold of the slope. The practical application shows that the treatment effect is obvious. The analysis method is simple and practical, which can provide reference for similar slope engineering analysis and management.
