摘　　要：为了防止云南红河复员村滑坡破坏坡下道路和坡上搬迁房屋。作者对该滑坡的岩性条件、人类工程活动、水文气象条件进行分析,研究滑坡诱发因素、滑坡的稳定性及失稳机理,并采用MIDAS/GTS NX数值模拟有限元软件,基于强度折减法(SRM)原理对边坡的稳定性进行分析。提出锚杆框架梁护坡+挡土墙护脚+护面墙封闭+排水工程的方案进行综合治理,并对治理后的边坡稳定性进行分析研究,为相关工程案例提供参考。In order to prevent the landslide of Honghe demobilized village in Yunnan Province from destroying the road below the slope and moving houses on the slope.The author analyzed the lithologic conditions,human engineering activities,hydrometeorological conditions of the landslide,studied the landslide induced factors,the stability and instability mechanism of the landslide,and used MIDAS/GTS NX numerical simulation finite element software,based on the strength reduction method(SRM)principle to analyze the slope stability.The comprehensive treatment scheme of anchor frame beam slope protection+retaining wall retaining foot+retaining wall closure+drainage engineering is proposed,and the slope stability after treatment is analyzed and studied,which provides reference for relevant engineering cases.
