| Abstract: | Based on the principle of soil-structure interaction, the FE-IE-INE model is adopted to simulate the layer structure, nonlinearity, and status of slipping, tension crack between soil and reinforced concrete wall. The introduction includes the principle of instituting contact interface element, the element stiffness matrix of parallel infinite element and the method of coupling the different element. Through the analysis of the response of a double hole with rectangle section to earthquake, suggestions are made on aseismic design. |
