摘要
采用基于Morgenstern-Price法的Monte-Carlo模拟对黄河大堤开封段边坡进行了可靠度分析,并用抽样法进行了考虑土性参数空间变异性的可靠度分析,讨论了土性参数互相关性对可靠指标的影响,得到了一些有益的结论。对边坡工程安全度评价研究有一定的理论意义和实际应用价值。
This paper incorporates the Morgenstern - Price method with the Monte - carlo simulation for reliability analysis of slope stability. The approach is further applied to the reliability analysis of the slope stability of the downstream levee on the Yellow River in Kaifeng. Sampling method is used in the reliability analysis. The spatial variability of soil parameters is taken into consideration. The paper further discusses the effects of the correlation of soil parameters on the reliability index. Some more reasonable results are obtained. The approach and results pres- ented in this paper are useful to the safety evaluation of slopes on Yellow River.
