摘　　要：根据加筋土挡墙的结构特点,利用Plaxis软件对不同加筋断面形式下的挡墙进行有限元数值模拟,得到各种断面下的水平变形、安全系数及潜在破裂面。通过对比分析得到加筋土挡墙满足安全经济性要求的合理加筋断面形式,为今后的实际工程提供了一种参考。According to the characters of reinforced earth retaining wall,the finite element numerical simu-lation of retaining wall with different fracture form was carried out by means of program Plaxis.The horizontal deformation,factor of safety and potential fracture plane were obtained.By contrastive analysis,the reasonable fracture of reinforced earth retaining wall was acquired,which was safe and economical.Then a applied reference was provided for the practical engineering in future.
