摘　　要：采用圆弧条分法计算得到对边坡率、抗剪强度指标、重度、地震力、地下水位、坡顶荷载等7种因素变异下的边坡稳定安全系数。通过正交试验分析得到边坡稳定计算参数的重要性规律。The safety factors of slope stability with different slope rates,shear strength indices,unit weights,seismic forces,groundwater levels and surcharges were calculated by the circular slice method.Mathematic al statistics used in that complex condition,some conclusions of the parameter significance of slope stability were drawn by analysis of orthotropic test.

关 键 词：圆弧条分法 边坡稳定性 重要性分析 正交试验
