摘　　要：青岩岭滑坡距离涪江铁笼堡水电站下坝址8 km,目前还存在变形迹象,水库蓄水后存在大规模失稳的可能。因此对滑坡进行稳定性分析及其塌岸范围预测十分重要。根据青岩岭滑坡的特征,综合运用刚体极限平衡和有限元两种方法,对滑坡在5种工况下的稳定性进行分析,并采用图解法预测坡体塌岸范围。Qingyanling Landslide is 8 km from the site of the lower darn of Tielongbao Hydropower Station on Fujiang River and an evidence of deformation is still there at present, and then it is possible to be destabilized in large scale therein after the im- poundment of the reservoir. Therefore, the analysis on the stability of the landslide and the prediction of its bank-collapse are quite important. In accordance with the features of Qingyanling Landslide, the stability of the landslide under 5 working condi- tions are analyzed herein by the comprehensive application of both the rigid body equilibrium limit method and the finite element method, moreover, the area of the bank-collapse is predicted with graphic method as well.
