摘要(Abstract)：

为了解岩体结构和岩体力学参数等对层状岩质边坡稳定性的影响规律,采用有限差分数值仿真软件Flac 3D计算了模型在不同岩体容重、泊松比、内聚力、摩擦角等因素作用下的边坡稳定安全系数,利用正交实验法和SPSS统计分析软件获知不同影响因素对层状岩质边坡稳定性的安全系数敏感程度及权重比例。计算结果表明:摩擦角、内聚力、容重、泊松比与边坡安全系数的变化规律接近于线性变化,对边坡稳定性影响权重从小到大依次为泊松比、容重、内聚力、摩擦角。
In order to understand the influence of rock mass structure and rock mechanics parameters on the stability of layered rock slope.The finite difference numerical simulation software Flac 3 Dis used to calculate the slope safety factor of the model under different rock mass density,Poisson ratio,cohesion force and friction angle.The orthogonal test method and SPSS statistical analysis software are used to know the sensitivity degree and weight ratio of different influencing factors to the stability of layered rock slope stability.The calculation results show that the friction angle,cohesion force,bulk density,Poisson ratio and slope safety factor are close to linear changes.The weights of the slope stability are from Poisson ratio,bulk density,cohesion force,and friction angle.
