本文试验验证了有限元强度折减法在加筋土边坡中寻找破坏面的可行性,用工程实例分析了3种设计方案,综合考虑安全性、经济性和施工难度选择方案a为最终设计方案;并探讨了摩擦系数对安全系数、筋带轴力和破坏面的影响。有限元强度折减法在60m高加筋土挡墙的成功应用为超高加筋土挡墙设计提供了重要的参考价值。
In this paper, the feasibility of finite element strength reduction method to find the failure surface in reinforced soil slopes is verified by experiments. Three kinds of design schemes are analyzed by engineering examples, considering the safety, economic and construction difficulty options a as the final design The influence of friction coefficient on the safety factor, the axial force of tendons and the failure surface is also discussed. The successful application of finite element strength reduction method in 60m high reinforced earth retaining wall provides an important reference value for the design of the ultrahigh reinforced earth retaining wall.
