摘　　要：介绍了一种衡量边坡稳定性的简化处理方法,采用蒙特卡洛法与极限平衡法,对某均质边坡进行了可靠度分析,并将简化方法的结果与已有结果进行了对比,结果表明:失效概率误差控制在20%以内,可以尝试采用简化方法对边坡进行可靠度分析。Introduces the simplified treatment for slope stability,Monte-Carlo method and limit equilibrium method is used to perform the reliability analysis of homogeneous soil slope. The obtained results are compared with those from the existing results. The comparison shows that the simplified method can yield the result within 20% error,so the simplified method can be used for slope reliability analysis.

关 键 词：边坡 可靠度 土体参数 空间变异性
