| 摘 要： | 根据水库边坡的勘察资料，确定了边坡稳定性分析的力学模型，推导了滑面面积的计算公式，采用不平衡推力传递法进行了边坡稳定的定值法分析和可靠度分析。可靠度分析中，分别讨论了滑面强度参数及几何参数的变异性对边坡稳定性的影响。计算结果表明，不考虑参数变异性的定值法分析结果所得边坡的安全系数过高，偏于危险。水库边坡的可靠度分析结果表明：滑面几何参数的变异性对边坡稳定的可靠指标或失效概率影响很大。因此，对于岩质边坡的稳定性分析，不仅要重视研究滑面强度参数的变异性，也要重视研究滑面几何参数的变异性。

| Abstract: | Based on the investigation data of the reservoir,the mechanical model of slope stability of the right bank dam shoulder is set up;and the computational formulas are deduced for calculating the cross-sectional area of each slip block.Then,slope stability analyses of both definite method and reliability method are carried out by using unbalance thrust force transfer method.The influences of the variability of shear strength parameters and geometric parameters of slip surfaces on slope stability are discussed ... |
