牛栏溪滑坡稳定性分析

2014年6月上旬，贵州省铜仁市思南县连续强降雨，造成兴隆乡兴隆村下牛栏溪、兴隆村巷子、木根坡村上牛栏溪三个组居民居住的坡体发生不同程度开裂变形，引发1处滑坡，严重影响了该地区人民的生命财产安全及当地的经济建设。为此，运用Geo-studio中的SLOPE/W模块，建立思南县兴隆乡牛栏溪滑坡的稳定性计算模型，查明该滑坡地质灾害的稳定性。在不同工况下进行稳定性计算，结果显示该滑坡是不稳定的，必须进行治理。

Analysis of Stability of Niulanxi Landslide

In early June 2014, the occurrence of persistent heavy rain in Sinan County, Tongren City, Guizhou Province caused the cracking and deformation of the slope where three groups of residents living in varying degrees, triggered a landslide, which seriously affected the people’s lives and property in the region and local economic construction. In order to avoid the occurrence of major geological disasters, this paper establishes the model for the stability calculation of Niulanxi landslide in Xinglong Town, Sinan County by SLOPE/W module of Geo-studio, and analyzes and calculates the stability of the landslide under the two conditions respectively. Results show that Niulanxi landslide is unstable and must be treated.
