采用有限元软件Plaxis建立模型,分析建造在软土地基上的加筋土挡墙的变形特征、力学性能、加筋体应力应变分布规律;改变模型参数研究加筋土挡墙的各个组成部分对各项性能的影响,找出影响加筋土挡墙性能的关键因素。分析结果表明,加筋土挡墙性能受加筋长度、加筋间距、加筋体刚度影响较大,工程应用时应合理考虑加筋最佳长度、最佳竖向间距及最佳抗拉强度。
The finite element software Plaxis was used to establish a model to analyze the deformation characteristics, mechanical properties and stress-strain distribution of the reinforced earth retaining wall built on the soft soil foundation. The model parameters were changed to study the influence of each component of the reinforced earth retaining wall The impact of various properties, identify the key factors that affect the performance of reinforced earth retaining wall. The analysis results show that the performance of reinforced earth retaining wall is greatly influenced by the length of reinforcement, the spacing of reinforced stiffeners and the rigidity of stiffened body. The optimum length of reinforcement, the optimal vertical spacing and the optimal tensile strength .
