核电站辅助厂房结构—地基土相互作用体系的地震响应

本文主要针对核电站工程中辅助厂房结构与地基土相互作用体系在地震荷载下的“平-扭”地震响应进行了分析。在假定核岛基础为明置基础和考虑在同一基础上有安全壳及另一个辅助厂房结构存在的条件下,建立了整个相互作用体系的运动方程。最后结合我国秦山核电厂辅助厂房结构进行了数值计算和分析。

The Dynamic Responses of the Soil-Auxiliary Buildings Structure Interaction System

This paper is concerned with the dynamic responses of the soil-auxiliary buildings structure interaction system in the nuclear power plant. The main distinguished feature of this study is that the extreme unsymmetry of the auxiliary buildings and reactor containment are considered. A Synthetical mechconical model for study is established. Finally, the analysis of the dynamic response of the Qinshan Nuclear Power Plant structure is taken as a simple example of applying this method and the numerical results are given.
