针对加筋土挡墙工程设计方法中存在的问题，从有限元计算分析的思路出发，研究分析了加筋土结构内部抗剪强度分布特征，提出了用强度代换的方法通过有限元手段分析加筋土结构内部应力和应变的一种新思路，称之为等效强度方法。认为由加筋材料和被加筋土体构成的结构为复合材料结构，并从复合材料的观点对其中土体和筋材的应力与应变关系进行了分析，阐述了应用等效强度法分析加筋土挡墙内部稳定性的新方法。

Focus on the problems of design method for the soil retaining wall engineering,the authors analyzed the mechanical feature of inner soil reinforced structure based on finite-element method,and developed a new solution,that called the Strength Replacement Method (SRM)for analy-zing the inner stress and strain of soil reinforced structure through FEM. The authors believed that soil reinforced structure was a kind of new com-posite material,the relationship of stress and strain with reinforce and soil as composite material was analyzed by the new solution,and the SRM was introduced to apply to the inner stability analysis of soil reinforced retaining wall at last.
