核电站地震易损性分析方法的研究进展
Methodologies for seismic fragility analysis of nuclear power plants: state-of-the-art
【摘要】 地震概率风险评估是核电站地震安全评估方法之一,其中地震易损性分析是地震风险评估方法中的重要一步。本文针对核电站地震易损性分析方法研究进展进行了全面综述:首先介绍了三种核电站地震易损性分布模型,叙述了地震易损性由于数据来源不同而形成的多种分析方法:解析易损性分析、设计易损性分析、试验易损性分析、经验易损性分析、专家判断易损性分析和混合易损性分析,然后列表总结了美国三种核电站易损性分析方法:Zion法、SSMRP法和BNL法,并对基于保守确定性失效裕度分析的混合易损性分析方法进行了简要介绍,最后对全文进行了总结和评述。
【Abstract】 Seismic probabilistic risk assessment,which includes seismic fragility analysis,is one of seismic safety evaluation methods for nuclear power plants. This paper gives a full review of the research progress of seismic fragility analysis of nuclear power plants: Firstly summary three distribution models of seismic fragility analysis for nuclear power plants; Secondly introduce some seismic fragility analysis methods based on different data sources,which include analytical fragility analysis,design fragility analysis,experimental fragility analysis,empirical fragility analysis,expert judgmental fragility analysis and combined fragility analysis; Thirdly summary three fragility analysis methods in America listed in the table: Zion method,SSMRP method and BNL method; Fourthly identify a hybrid fragility analysis method based on conservatism deterministic failure margin analysis; Finally full contents of seismic fragility analysis methods are summarized and discussed.
