摘　　要：目前对岩质边坡安全系数计算方法有多种,其合理的选用日益受到人们的重视。运用刚体极限平衡方法和有限元法对工程中常见三种破坏类型(圆弧形、直线形、折线形)进行了稳定性分析,并对这些方法计算的结果作了对比研究,从中得到边坡安全系数的变化规律,为工程提供了参考。Recently, there are several calculation methods for the safety factors of rock slope. The people＇s attention is attracted to the reasonable selection for them day by day. Here the stability of the three con＇anon failure modes （the type of arc, the type of beeline, the type of folded line） is analyzed with LEM and FEM, then the relative comparison and research are made for the calculation results, from which some variation rules of the safety factors of the slope are gotten to provide some useful references for some projects.

关 键 词：岩质边坡 极限平衡法 有限元法 安全系数 破坏类型 对比
