摘　　要：针对不稳定路堑边坡影响道路安全问题,根据规范要求应采取有效的边坡支护方法保证边坡及环境安全。文章结合具体路堑边坡工程实例,按照工程建设要求以及地质条件,将该路堑边坡分为8阶,采取弱层削除、坡面喷浆以及锚杆支护的加固方式提高边坡稳定性。基于强度折减原理和有限元法分析理论,以数值模拟结果证明该加固方法有效提升路堑边坡稳定性及其使用年限。According to the problem that unstable cutting slope impact the safety of the road,some effective reinforcement methods should be adopted to ensure slope and environmental safety.Combined with an engineering example of the cutting slope,it was divided into 8 steps and the slope stability was improved by cutting the incompetent bed,spraying mortar for the slope surface and supporting of anchor bolt,in accordance with the requirements of engineering and geological conditions.Based on the theory of FEM and strength reduction,it showed the reinforcement method improved the stability and useful life of the slope effectively with the analysis result of numercial simulation.
