摘　　要：用谱分析法分析了低功率堆堆本体抵御七度和八度地震的能力,并与实验相结合,讨论了基础对结构动力特性的影响。将基础考虑为弹性支撑,求出结构在实际状况下的响应。并用此结果校核了地脚螺栓的强度。最后评述了堆本体的抗地震能力。In this paper,the response spectra method is used to analyzethe aseismic performance of the reactor structure when the 7 and8 degree earthquake takes place.In order to discuss the effect ofthe foundation,the experiment result is quoted.It is more res-onable to consider the foundation as elastic support.thus,theactual result is got.Using the result,the seismic safety is given.
