本文应用概率论及数理统计为理论基础的结构可靠度分析方法,对双斜滑动面岩基上重力坝的抗滑稳定安全指标的计算进行了探讨。并结合算例分析了各变异系数对该可靠指标的影响,取得了较为满意的结果。
In this paper, the method of structural reliability analysis based on the theory of probability and mathematical statistics is used to calculate the anti-slide stability and safety index of the gravity dam on the double-inclined slide surface. The influence of each coefficient of variation on this reliable index is analyzed with an example, and the satisfactory result is obtained.
