According to the analysis of La Mu-gu landslide of Shang-jiang town in Shangri-La County, the formation process is described from the aspects of landslide area engineering survey, landslide form, deformation and sliding zone. Take the quantitative evaluation of the stability of the typical profile and its sub condition, and combined with the actual put forward control measures of the landslide. Analysis results show that:the whole slope is basically stable and unstable state in the rainfall and engineering, the slope is in an unstable state, and the stability of the landslide has a deteriorating trend, it is advisable to take measures for the landslide. Specifically, measures can be taken:in the front of the landslide, the retaining structure is provided with a supporting block, and the supporting structure is further under the potential sliding surface; effective interception and drainage system on the periphery of slope body, which can put the rain and discharged outside the slope catchment;dynamic monitoring of landslide.%针对香格里拉县上江乡拉木古滑坡进行稳定性分析,从滑坡区工程概况、滑坡形态、变形迹象、滑动带特征等方面叙述形成过程.选择典型剖面及分工况定量评价其稳定性,并结合实际对该滑坡提出治理措施.分析结果表明:整个坡体处于基本稳定-不稳定状态,在降雨及工程活动下,整个坡体处于不稳定状态,且滑坡稳定性有进一步恶化的趋势,因此建议对该滑坡采取治理措施.具体而言,可采取的措施主要有:在滑坡中前部设支挡构筑物支挡,支挡结构深入到潜在滑动面之下;坡体后缘外围(后部约20m)设有效的截排水系统,把雨水和坡面汇水排出坡外;加强滑坡的动态监测等.
