Stability Analysis of Loess Slope Reinforced by Prestressed Anchor Cables under Rainfall Infiltration

Abstract

Reinforcement of slopes with prestressed anchor cables is an important means to improve the stability of slopes. In order to analyze the stability of the anti-slide piles reinforced by prestressed anchor cables under rainfall infiltration, the MIDAS/GTS simulation software was used to compare and analyze the stability of loess slopes without seepage based on the strength reduction method. Different anchor cable lengths, The influence of six factors including inclination angle, anchoring force, anchoring position, rainfall intensity and rainfall duration on slope stability, and using orthogonal design method to analyze the sensitivity of each factor. The results show that under rainfall infiltration, the anchor cable support parameters have different effects on the slope stability, and the anchor cable length has the highest sensitivity. The rainfall intensity, inclination angle, rainfall duration, anchorage position, and anchorage force have different effects on the slope stability. The impact of the decrease in order.
