本文利用作者提出的考虑土性非线性与基础翘离两种非线性效应的土─结构相互作用集中参数模型，建立了土─结构体系的运动方程，以一座核电厂安全壳结构为例进行了地震反应参数研究；讨论了不同地基土剪切波速与输入地震加速度条件下土─结构线性与非线性相互作用对结构反应的影响。
In this paper, by using the concentration-soil-structure interaction parameter model which considers two nonlinear effects of soil-based and foundation-set-off proposed by the author, the equations of motion of soil-structure system are established. Taking a nuclear power plant containment structure as an example The seismic response parameters are discussed. The effects of soil-structure linear and nonlinear interactions on the structural response under different ground shear wave velocities and input earthquake accelerations are discussed.
