摘　　要：通过对汶川地震、通海地震、唐山地震和澜沧-耿马地震中水利工程破坏情况的统计分析,本文以统计表的形式直观地反映了水利工程震害的特点及破坏形式。根据水利工程的震害特点,探讨分析了水利工程震害的主要影响因素,结果表明地震烈度、结构设计、施工质量、地基及场地条件是水利工程震害的主要影响因素。基于水利工程震害的特点及主要影响因素,探讨了水利工程的抗震措施,并对今后的抗震工作提出了一些建议。Through statistical analysis of seismic damage of hydraulic projects after large earthquakes of Wenchuan, Tonghai, Tangshan and Lancang-Gengma, the characteristics of seismic damage in hydraulic projects is obtained by the intuitive form of statistical tables. According the seismic damage characteristics of hydraulic engineering, we discussed the main factors of seismic damage in hydraulic projects. Our results in this paper showed that seismic intensity, structural design, construction quality, foundation and site condition are the main factors of seismic damage in hydraulic projects. Finally, we proposed some anti-seismic measures and recommendations in future seismic resistance work for hydraulic projects.
