摘　　要：杨家坪滑坡位于湖北省兴山县,当三峡水库蓄水后,水库回水可能诱发滑坡失稳.由于滑坡规模巨大,潜在危害严重,对其实施工程治理十分必要.针对杨家坪Ⅱ号滑坡进行稳定性分析及工程治理设计.以地质勘查为主,结合工程类比等手段,确定滑坡稳定性计算的物理力学参数;以Geo-Slope为工具,选取滑坡典型剖面,对其稳定性及剩余推力进行计算;根据滑坡稳定现状及其地形地貌特点,提出以连续梁锚索加格构为主的综合治理措施.本文对类似工程具有一定的参考价值.Abstract Yangjiaping Ⅱ landslide is located in Xingshan County, Hubei province. After the impounding of Three Gorges Reservoir,it may be triggered by the reservoir water. In order to prevent the serious potential hazard, the mitigation and control project is necessary. This paper analyzes the landslide stability and propo- ses the engineering controlling measures for it, and derives the physico-mechanical parameters of landslide materials by geological exploration, experiment and engineering analogy. And by choosing the typical land- slide profile, it analyses the landslide stability and residual thrust force by Geo-Slope processing. According to the landslide stability situation and landform characteristics, it proposes the controlling measures such as con- tinuous girder cable and lattice beam. The results have a certain reference value to some similar engineering projects.
