摘　　要：针对土工格栅加筋土结构,提出一种土与土工格栅筋材相互作用界面模拟的新思路。通过工程算例对加筋土地基的极限承载力进行了研究。分析了加筋深度、层数、间距等因素对加筋地基极限承载力的影响。According to the reinforced soil structure of the geo-grid, this paper presents a new thought of soil and geo-grid materials interactive interface simulation.By this way, the bearing capacity of reinforced soil foundation is researched by FEM.The effects of the number of layers of reinforcement, the depth below the footing of the first layer of reinforcement and the vertical spacing of the layers on the bearing capacity are analyzed.
