用数值仿真软件Abaqus模拟包裹式加筋土挡墙与填筑体的动力相互作用。建立土工格栅与填土以及墙面板与土体之间的接触,用无限元做土体边界,土工格栅采用拉杆模型,土体采用Drucker-Prager模型,混凝土面板采用弹性模型。研究模型在6、7、8共3个不同等级的地震烈度作用下,土体、土工格栅和墙面板的变形规律、内力变化等。
Numerical simulation software Abaqus was used to simulate the dynamic interaction between the wrapped reinforced earth retaining wall and the filling body. The establishment of geogrid and fill and the contact between the wall panel and the soil body, using the finite element to make the soil boundary, the geogrid adopts the rod model, the soil adopts the Drucker-Prager model, and the concrete panel adopts the elastic model. The deformation and internal forces of soil, geogrid and wall panel are studied under the seismic intensity of 3 different levels of 6, 7 and 8.
