摘要
应用有限差分软件FLAC 3D对有实测工程资料的加筋挡土墙进行数值模拟,在数值模拟的基础上通过改变加筋的加筋挡土墙来研究加筋长度对挡土墙工作性态的影响,通过模拟分析表明挡墙面板侧向位移及加筋层拉应力随着加筋长度的增加而减小,且筋材的最大拉应力集中在加筋挡土墙的底部,可能剪切破坏面随着加筋长度的增加而向远离面板的方向移动。
A finite difference software （FLAC 3D） was used to carry on numerical simulation of reinforced retaining wall which had engineering observed data. To chang the length to study the effect of the reinforced length had on retaining wall. The simulation and analysis showed that as the increase of reinforced length, the side displacements of the panel and tension of reinforced layer decreased gradually. The maximum tension of the reinforcing steel focused on the bottom of the retaining wall, and as the increase of reinforced length, the destroyed cross because of shear stress mav move awav from the panel.
