摘　　要：某核电站厂房由于工艺需要进行设计改进,作为翻版设计的核电站需要评估此设计改进厂房的地基适宜性。基于美国ASCE 4-98《核电结构的地震安全性分析及解说》推荐的集总参数地基模型,针对一系列的均质场地,计算了设计改进厂房典型楼层的反应谱,评估此设计改进对该核电站厂房地基适宜性的影响。计算结果表明:对于剪切波速大于1 500 m/s的均质场地,此设计改进厂房是完全适宜的。The design improvement of the nuclear power plant building is carried out due to the technology requirement. The evaluation of site adaptability of this NPP building as the reproduction design is needed. In this paper, the typical floor response spectrum（FRS） of the NPP building was calculated based on the lumped parameter models recommended by seismic design codes of ASCE 4 - 98 aiming at a series of homogeneous field. It can be concluded that the uniform site whose shear wave velocity is more than 1 500 m/s, is entirely appropriate for this design improvement NPP building.
