摘　　要：采用了复合材料理论和有限元方法，对加筋土结构进行非线性分析，分析时把土体视为非线性单元，把筋带视为线性单元，为了研究筋、土之间的滑动性质，应用接点滑动单元，同时考虑了墙面位移、筋带变形的影响；计算值与模型试验实测值相吻合，表明该方法正确有效。Using compound material theory and finite element method, the reiforced earth structure hasbeen analyzed nonlinearly. Filler soil was looked as nonlinear continuous unit, and strip as linearunit. For research slipe behavior between filler and strip, joint sliped unit is been used. Wallsurface deformation and strip strains are considered during analyzing. Analysis results are in goodagreement with model test, so the method can be considered as available one.
