| 摘 要： | 提出了一种改进的土－结构相互作用非线性分析的集中参数模型。模型中考虑了两种非线性效应－土性非线性以及基础和周围土体局部脱离接触所引起的几何非线性，同时，对竖向振动以及水平与回转振动的耦联加以考虑，最后，对分析结果和试验结果进行了对比。

| Abstract: | A modified lumped parametric model for the analysis of nonlinear SSI effects has been proposed. In the model two kinds of nonlinearities are considered:those associated with inelastic soil behavior and those resulting from loss of contact between the foundation and the surrounding soil. And the rocking mode of the response is coupled with both horizontal and vertical.At last comparision has been made between the results of model tests and those obtained by the proposed model. |
