基于Autobank的膨胀土边坡稳定性分析
Stability analysis of expansive soil slopes based on Autobank
摘要
Abstract
Expansive soil,characterized by its tendency to swell upon water absorption and shrink upon dehydration,makes slopes highly susceptible to instability under rainfall infiltration.This study selected a typical expansive soil slope from the Simashan Yangtze River diversion irrigation project as the research subject.Using Autobank software,the impact of rainfall in-filtration on the slope's anti-slide stability was simulated,and the stability changes after reinforcement with a retaining wall were analyzed.The results indicated that rainfall infiltration caused the safety factor of the slope's most critical slip surface to decrease from 1.375 to 1.210,with the potential slip surface tending to be shallower and the sliding mass volume reduced.Af-ter reinforcement with the retaining wall,the slope stability improved significantly,increasing the safety factor of the original potential slip surfaces by 28.22%and 34.96%,respectively.These findings provided critical technical support for the stabiliza-tion and management of expansive soil slopes.关键词
