| 摘 要： | 结合已有试验数据对堆石料的抗剪强度参数进行了统计分析，分别采用验算点法和统计矩法对面板堆石坝下游坝坡的稳定性进行了可靠性分析，结果表明了这两种方法在面板堆石坝边坡稳定可靠性分析中的适用性；进而以洪家渡面板堆石坝为算例，对其抗剪强度参数的统计量进行了敏感性分析，说明了对面板堆石坝边坡稳定性进行可靠性分析的必要性，对可靠性理论在岩土工程中的应用进行了有益的尝试。

| Abstract: | Based on the experimental data available for Hongjiadu concrete-faced rockfill dam, statistical analyses for shear strength parameters of rockfills are made. Then the statistical method of moment and the first-order second-moment method are respectively employed to assess the reliability of stability of downstream slope of the dam. In addition, sensitivity analyses of the statistical characteristic variables of shear strength parameters are conducted to discuss the effects of soil cohesion and friction angle on the reliability index. This study will be helpful to the application of reliability theory to geotechnical engineering. |
