基于Monte-Carlo模拟的公路黄土高边坡可靠性研究

Reliability Analysis on Highway Loess Slope Stability Based on Monte-Carlo Method

本文分析了Monte-Carlo模拟法的基本原理,建立了基于简化Bishop圆弧法的极限状态方程;以陕西公路某黄土路堑高边坡为例,分析了模拟次数、计算模型以及土性参数的变异系数对可靠指标的不同影响,从而为公路黄土路堑高边坡可靠性分析提供了参考依据。

In the paper,the basic principle of Monte-Carlo simulation law is analyzed,and the limit state equation is set up on the basis of simplifying Bishop arc law.Taking one loess cutting high slope of highway in Shaanxi as an example,analyzed the different influences on the reliable index caused by simulation number of times,calculation models,coefficients of variation of the soil parameters,which can be used as reference for the loess cutting of the highway high slope.
