【摘要】 对AP1000抗震分析与设计的主要特点进行分析,并将这些特点同现有核电站的设计状况和我国潜在厂址的情况进行对比。研究侧重于抗震分类、抗震设防水准及设计地震、地基岩土条件、抗震裕度分析等几个主要方面。通过研究,把握AP1000抗震分析与设计的主要特点,对其设计特点和适应性加深理解,并提出需要继续跟踪研究和关注的问题。研究成果可以为后续研究和AP1000堆型的工程引进提供参考和基础素材。其中关于抗震裕度分析的研究内容对于在我国开展在役核电厂的地震安全评估和3级PRA分析亦有借鉴意义。更多还原

【Abstract】 The major features of seismic analysis and design of AP1000 are studied,which are compared with the relatives of an existing nuclear power plant and with actual situation of a potential site in China.The important issues for the seismic design and safety evaluation of a nuclear power plant are emphasized in this article,namely seismic categories,response spectra of design ground motion,soil conditions and seismic margin analysis.As better understanding about the major characteristics of the seismic analysis and design of the nuclear power plant,the preliminary evaluation conclusions on the technical issues and maturity of AP1000 seismic design,and also some suggestions for the successive study and engineering implementation are raised.And the research contents with related to seismic margin analysis of AP1000 would be provided some useful references to the seismic safety evaluation and Level 3 PSA for an existing nuclear power plant.更多还原
