摘　　要：针对公路路堑边坡的风险评估问题,分析《高速公路路堑高边坡工程施工安全风险评估指南(试行)》存在的不足,对边坡施工风险总体评估方法进行优化研究。提出修正指标体系法和专家调查法,新增了对边坡风险等级有影响的信心指数分级、不良地质条件、施工方案等因素。经实体工程验证,优化方法更适用于高速公路路堑高边坡工程施工总体风险评估工作。In relation to the risk assessment of cutting slope,herein the shortcomings of Guide for Risk Assessment in Construction Safety for Highway Cutting High Slope Engineering(Trial)were analyzed,and the optimization study on the general risk assessment method for slope construction was made in such manner that the revised index system method and expert investigation method were proposed,and the factors influencing the slope risk rating,such as confidence index rating,undesirable geological conditions,and construction scheme,were included additionally.It was proved by solid engineering works that the optimization method was more applicable to general risk assessment in construction of highway cutting high slope.
