Abstract
Based on the rock mass parameter of left bank slope of Jinsha river hydropower station,the influence of slope height、slope angle、dip angles of layer、mechanical parameters of layer and angle between layer and slope on stability and collapse of toppling slope were analyzed with orthogonal analy-sis using UDEC.The results show that each of the above factors have influence on the stability and collapse of toppling slope,the influence of mechanical parameters of layer is particularly significant;It is found when the slope angle less than 40°and dip angles of layer less than 50°,the failure trend of the slope collapse is not obvious,when the slope angle more than 40°and dip angles of layer more than 50°, the failure trend of the slope collapse increased significantly,slope failure mode is disjunction;the angle between layer and slope also has great influence on the stability and collapse of toppling slope,the slope failure mode transition from disjunction to arc-shaped sliding failure with increasing of the angle between layer and slope when angle with levels at 0°~90°.关键词
