| 摘 要： | 将地震效应以水平地震加速度的形式引进土坡的稳定性分析中，根据土条的受力平衡条件导出了任意形状滑裂面下土质边坡的安全系数表达式，并进行了稳定可靠度分析。以石家庄地区某一边坡为例，分析了土性参数和地震效应对边坡稳定性的影响。计算结果表明：土体强度指标的变异系数和地震加速度系数的变化对土坡的安全影响较为显著，对土坡的分析研究有重要意义。

| Abstract: | Horizontal earthquake acceleration is used for the analysis of earth slope reliability. For the slope slices, force equilibrium equations are developed and the formulas of the earth slope safety factor are derived and the reliability is then studied. In the case of a slope in Shijiazhuang area, calculation results show that the safety factor with the stochastic earthquake has close relation with the earthquake acceleration and the soil property. It is clear that the influence of the earthquake is notable. |
