摘要
基于可靠度分析理论,利用蒙特卡洛法,对某土坡可靠度稳定性进行数值模拟,分别进行了系统可靠度和常规可靠度分析,讨论了粘聚力和摩擦角相关性对失效概率的影响,并将二者进行对比,分析结果表明:系统可靠度分析比常规可靠度分析方法所得的结果偏大。
A numerical simulation of the reliability for a soil slope is conducted with the theory of reliability analysis and Monte Carlo simulation method.The results from system reliability analysis are compared with those from the traditional reliability analysis correlation effects of cohesion and friction angle for soil layer has been discussed.The results show that the results from system reliability analysis is larger than that from traditional reliability analysis.
