运动学和极限平衡法相结合边坡稳定性分析

本文根据非洲如瓦西矿西南边坡为案例,分别采用运动学分析方法和极限平衡法,对边坡稳定性进行分析研究。研究结果表明:西南边坡发生平面滑坡和楔形体滑坡的概率较小,但由于边坡部分岩体较破碎,结构面较发育,不排除小规模楔形体滑坡的可能。极限平衡法计算的最小安全系数均高于规范要求值,其边坡为稳定边坡。

Based on Kinematic Analysis and Limit Equilibrium Method to Analyze the Slope Stability

Based on the case of Ruashi southwest slope in Africa,kinematic analysis method and limit equilibrium method are used to analyze the stability of the slope.The results show that the probability of Planar Sliding and Wedge Sliding is small in the southwest slope.The possibility of small-scale Wedge Sliding may occur,which is due to the fracture of some rock mass and the well development of structural plane.The minimum safety factors calculated by limit equilibrium method are higher than the standard value,and the slope can be considered stable.
