摘要
所研究滑坡位于四川东部某市境内,滑坡变形分布较为零散,规律性相对较差。鉴于该滑坡紧邻市区,危害严重,对其进行了成因机制的分析及稳定性的评价研究,以期为该滑坡的防治与治理工程提供科学依据。该滑坡为一小型土质顺层古滑坡体,受下覆基岩面的控制和滑坡体西北侧开挖临空面的影响,滑坡发生沿S82°W方向的滑动,同时向临空面产生方向约为N37°W的局部次级滑动。稳定性分析结果表明,在暴雨工况下,该滑坡将沿主滑方向发生失稳。
The Landslide studied is in Bazhong Sichuan. The distribution of deformation is very scattered and ruleless. For this landslide is close to the town, and it may be result in serious hazard, the stability and formation mechanism of this landslide is studied, in order to provide scientific foundation for the engineering of prevention and controlling. For the influence of bedrock surface, the main slide direction of the landslide is S82°W, and at the same time, there are local deformations in the direction of N37°W. The result of analyses of stability shows that the landslide is very dangerous when it is storm.
