【摘要】 在边坡稳定性分析中，把岩体强度参数视为随机变量来处理，考虑边坡工程的风险，用工程类比法确定出整体边坡允许破坏概率和目标可靠性指标，从而选择最佳边坡设计方案。笔者认为，破坏概率与安全系数值是不同范畴的概念。可靠性分析方法充分考虑到了各种影响边坡稳定性因素的变异性，其计算结果更为可靠和适用。更多还原

【Abstract】 In this paper, in the rock slope stability analysis, the strength parameters of rock masses areregarded as random variable parameters. Considering the rock slope risk and using engineering analogousmethocl, the permission failure probability and reliability index are determined. Thus, the optimum rockslopes are selected with the above results for designers.The failure probability is different from safety factor, and the calculating results of reliability analysisare more reliable and useful. because they consider more factors which influence on the rock slope stability.更多还原
