摘　　要：以某高边坡为研究对象,确定边坡坡率进行放坡处理和加固设计,采用蒙特卡洛概率分析法对边坡放坡后和治理后的稳定性进行分析,并与传统的极限平衡法计算结果进行了对比,两种计算方法具有相当的一致性。蒙特卡洛概率分析法能较为准确、全面评价边坡的稳定性,同时也是对传统极限平衡分析的进一步验证。Taking the PANMEI high slope as an example, the slope gradient was determined for slope treatment and reinforcement design, and the slope stability after slope treatment was studied by means of Monte Carlo probability analysis and then the result calculated by traditional limit equilibrium method was compared. The considerable consistency was found between these two methods. However, Monte Carlo probability analysis, as a method evaluating slope stability correctly and comprehensively, could further verify limit equilibrium method.
