摘　　要：云南省境内膨胀土分布较广,膨胀土遇水膨胀失水收缩的特性使挖方边坡极易失稳。本文通过对膨胀土边坡失稳机理进行分析探讨,并结合工程实例给出膨胀土边坡稳定性计算参数取值原则,供勘察和设计人员参考。Expansive soil is widely distributed in Yunnan Province,and the characteristics of expansive soil expansion and shrinkage when encountering water make excavation slopes highly susceptible to instability.This article analyzes and explores the instability mechanism of expansive soil slopes,and provides the principles for calculating the stability parameters of expansive soil slopes based on engineering examples,for reference by survey and design personnel.
