摘　　要：膨胀土吸水、失水产生膨胀、收缩的胀缩特性导致膨胀土边坡频繁出现崩塌事故。论文以云南蒙自某基坑边坡失稳为例,分析工程各阶段导致事故影响因素,介绍了应急及加固处理措施,供膨胀土区域类似工程参考。The expansive soil swells and shrinks after water absorption and loss,resulting many expansive soil slope collapse.Taking the slope instability of a foundation pit in Mengzi,Yunnan Province as an example,analyzed the influencing factors leading to the accident at each stage and introduced the concrete emergency reinforcement measures.It provides reference for foundation pit construction in similar expansive soil area.

关 键 词：膨胀土 基坑边坡 边坡失稳 加固处理
