| 摘 要： | 从桩-土-结构在地震作用下的受力分析出发,考虑平面应变假设,用有限元法(FEM)建立相互作用系统的模型。文中用地震动反演法处理土层的动力放大现象,用读入刚度单元来处理不同类型单元交界处的连续问题。最后,结合实际工程进行相互作用体系的地震反应计算,得出了一些有用的结论。

| Abstract: | In this paper,based on the assumption of plane strain, a mechanical model on the dynamic response of pile-soil-structure is set up by finite element method(FEM). Earthquake inverse method is used to solve the dynamic amplification phenomenon of soil. Input-stiffness matrix unit is used to settle continuous conditions of the different type of connective unit. Finally, through the seismic analysis of a six-storied building, some useful conclusions are obtained. |
