摘　　要：基于强度折减法和重力增加法分别对未加筋边坡和加筋边坡进行了有限元数值分析,并与Bishop法进行了对比,验证了将这两种方法应用于加筋土边坡计算的可行性。通过对工程实例的计算分析,建议对于未加筋边坡将坡内点的水平位移急剧变化作为边坡处于临界破坏状态的判别标准;而对于加筋土边坡,将塑性区从坡脚至坡顶贯通作为临界破坏状态的判别标准。Based on the strength reduction and gravity increase method, this article made a finite element numerical analysis of unreinforced slope and reinforced slope, which were compared with the Bishop method to validate the feasibility of these two methods used in reinforced slope calcula- tion. Through the analysis of project, it is recommended that the dramatic changes of level shift to be the critical state criterion of unreinforced slope, and the plastic zone from the slope foot to the slope top through to be the critical state criterion of reinforced slope.
