边坡工程是岩土领域研究的热点和难点，边坡工程的状态涉及众多参数，具有不确定性，可靠度理论能利用数学方法将边坡工程中随机不确定的参数与工程的安全性有机联系。以元磨高速公路K253＋（400～560）段为例，通过Bishop法，运用极限平衡理论建立极限状态模型，进而推导极限状态方程；并利用Geo-studio对不同时段中边坡的降雨入渗情况进行分析，选取最不利状态为风险评价对象进行可靠度分析，验证JC法在边坡工程风险评价方法的可行性；同时对影响可靠度指标的变量进行敏感性分析，建议在此类地层相似的边坡加固方面，应该以主要提高土层整体的内摩擦角为主，在此基础上采取提高边坡岩土的黏聚力的治理措施更为有效。

Slope engineering has increasingly become a hot and difficult problem in Geotechnical engi-neering 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 safe-ty 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 limit equilibrium 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 analysis for risk evaluation was done by selecting the most unfavorable state.The feasibility of the JC method for slope engineering risk assess-ment methods was verified.The variables affecting the reliability index were analyzed.Suggestion of strengthening the slope should be the main improving soil overall internal friction angle,and then to im-prove the cohesion of rock and soil slope treatment measures is more effective.
