基于Monte-Carlo法的边坡可靠性分析∗

摘要

The analysis process is achieved by MATLAB based on studying the effect of soil parameters in the coefficient of cohesion and internal friction angle of slope reliability indicators, on the basis of the principle of Bishop traditional limit equilibrium method, combined with the reliability analysis methods monte-carlo meth-od. The results showed that the coefficient of variation coefficient of cohesionδc and the variation coefficient of angle of internal friction δφare negatively correlated with the reliability index β.%为了研究土性参数中粘聚力系数c和内摩擦角φ对边坡可靠度指标β的影响，在传统的极限平衡原理Bishop法的基础上，结合可靠度分析方法中的Monte-Carlo法，通过MATLAB来实现以上的分析过程。结果表明：粘聚力系数c的变异系数δc以及内摩擦角φ的变异系数δφ与可靠度指标β呈负相关。
