Abstract: Slope engineering has increasingly become a hot and difficult problem in Geotechnical engineering field.The stability of slope engineering is determined by lots of parameters that are not sure.The theory of reliability can combine the random, uncertain parameters in slope engineering with the safety of engineering via mathematical methods. In this paper,the Yuan-mo Highway Slope K253+(400~560) was taken as an example by Bishop method, using limite quilibrium theory to establish the limit state model,and then derive the limit state equation. Then at different times of the slope of the rainfall infiltration cases were analyzed by using a Geo-studio. Reliability analys is for risk evaluation was done by selecting the most unfavorable state.The feasibility of the JC method for slope engineering risk assessment methods was verified.The variables affecting the reliability index were analyzed. Suggestion of strengthen ing the slope should be the main improving soil overall internal friction angle, and then to improve the cohesion of rock and soil slope treatment measures is more effective.
Key words: reliability, JC method, sensibility, failure probability
