摘要
通过将加筋挡墙结构离散成土体单元、格栅单元和接触单元,采用三维快速拉格朗日分析(FLAC3D)有限差分程序对土工格栅加筋挡墙进行了数值计算,得出了挡墙变形分布规律和筋材的受力性状.结果表明此方法合理,具有一定的实用性.
In this paper, the structure model of the geogrid reinforced soil retaining wall is made of soil element, geogrid element and contact element. The geogrid reinforced soil retaining wall is calculated by the FLAC^3D, a program of three dimensional finite difference analysis. At the same time, the law of the deformation distribution of the retaining wall and the stress state of reinforcements are obtained. The results show that the analytical method is reasonable for the reinforced soil retaining wall and is valuable in application.
