摘　　要：基于历史地震的海量震害数据建立经验性地震易损性曲线是我国防震减灾工作的重要内容。结合相当数量的文献,系统梳理了国内外经验性地震易损性曲线的研究进展及有关的规范或标准,剖析了经验性地震易损性曲线建立过程中房屋建筑分类、破坏等级划分、地震动参数选择、曲线拟合等各个环节存在的不足,结合现代灾害调查手段,提出了优化和扩大震害数据、合理选择地震动参数、标准化经验性地震易损性曲线的建立流程等建议。Establishing empirical seismic fragility curves based on massive seismic damage data from historical earthquakes is an important part of earthquake prevention and disaster reduction work in China.Combined with a considerable amount of literature,the research progress on empirical seismic fragility curves and relevant codes or standards at home and abroad were systematically sorted out,and the shortcomings of each link in the establishment of the empirical seismic fragility curves,such as buildings classification,damage states division,selection of ground motion parameters,and curves fitting,ect.were analyzed.Combined with modern disaster investigation methods,suggestions for optimizing and expanding seismic damage data,selecting ground motion parameters reasonably,and standardizing the establishment procedures of empirical seismic fragility curves were put forward.
