摘要
结合已有试验数据对断层抗剪强度参数进行了统计分析,采用蒙特卡罗法对小湾水电站进水口边坡的稳定性进行可靠性分析。结果表明了蒙特卡罗法在进水口边坡稳定可靠性分析中的适用性;进而以小湾水电站进水口边坡为算例,对其抗剪强度参数的统计量进行了敏感性分析,说明了对小湾水电站进水口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。
Based on the experimental data available for Xiaowan Hydropower Station water inlet slope, statistical analyses for shear strength parameters are made. Then the Monte- Carlo＇s method is employed to assess the reliability of stability of Xiaowan Hydropower Station＇s water inlet slope. 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.
