| 摘 要： | 考虑了岩体边坡滑动破坏的渐进特点，并将岩体的强度参数作为随机变量，研究了单块岩石稳定性的概率分析方法及考虑岩块间相互作用时岩体边坡整体稳定性的分析方法，提出了可靠度计算公式；最后通过算例研究了岩体强度参数的离散性对边坡稳定可靠度的影响．结果表明破坏概率与破坏转移概率密切相关，岩块间的相互作用对边坡的整体稳定性有较大的影响．

| Abstract: | The probabilistic analysis methods for the stability of a single block of rock and the rock volume in which the interaction between rock blocks is taken into account are investigated,and the reliability calculation formulas are presented. In the analysis,the progressive failure character of rock slopes is considered and the strength parameters of the rock mass are taken as random variables. Finally, the example shows that the failure probability is closely related to the failure transition probability,and the interaction between rock blocks is of great influence on the stability of rock slopes. |
