| Abstract: | 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. |
