Analyzing and Comparing the Dynamic Response of Test Reactor Main Workshop
【摘要】 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。
【Abstract】 : Analyzing soil- structure interaction is an important section in anti- seismic design and analysis of nuclear engineering.The factors that influence on the response of nuclear structures include 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.In this paper,the FLUSH program and SASSI2000 are applied to dynamic analysis.Moreover,comparing the obtained data and diagrams draws some conclusions.
