摘　　要：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 the paper based on the modified parametric model proposed by the authors of the paper for the soil-structure interaction analysis,in which the nonlinear effects of both the inelastic soil behavior and the separation of basement from soil are taken into consideration,the motion equations of the structure-soil system are established. The numerical results of parametric study on the seismic response of a typical R. C. containment structure in a nuclear power plant are described and then under the condition of different shear wave velocity of the soil and different acceleration level of the input ground motion the effects of linear and nonlinear soil-structure interaction on the structural response are discussed.
