Analyzing and Comparing the Dynamic Response of Test Reactor Main Workshop

土壤-结构动力相互作用分析是核工程抗震设计与安全分析中的重要环节。核工程在地震动中的反应主要取决于地震动特性、地基土特征与结构特性三个方面。对于非岩石地基土，由于构筑物基础面的运动受到土壤-结构动力相互作用的影响，与地表自由场运动会有显著的差别。在抗震设计规范中要求考虑这一相互作用的影响。本文采用 FLUSH、 SASSI2000程序进行了试验堆土壤-结构的动力分析，给出试验堆厂址地表自由场运动与各楼层反应谱，以供结构与设备抗震设计之用，并进行了比较分析。

Analyzing soil-structure interaction is an important section in anti-seismic design and analysis of nuclear engineering. The factors that influence the response of nuclear structures including the properties of earthquake, soil and structures. So the soil-structure interaction in the non-rock foundation is different from that in the surface free field, and the interaction must be considered under the anti-seismic design standard of test reactors. The FLUSH program and SASSI2000 are applied to dynamic analysis. Moreover, comparing the obtained data and diagrams some conclusions are drawn.
