摘　　要：强震区超高心墙堆石坝地震残余变形、地震孔压增长及地震破坏模式的分析研究和安全评价指标,以及采取的抗震措施是心墙堆石坝防震抗震研究及设计中的关键问题。在总结当前心墙堆石坝防震抗震研究的基本方法及关键技术基础上,以长河坝、双江口水电站砾石土心墙堆石坝为例,对防震抗震研究及设计的关键问题进行探讨。The key issues in seismic research and design of ultra-high core rockfill dam in meizoseismal area include the analyses of seismic residual deformation, seismic pore water pressure and seismic failure mode, the safety evaluation index and the earthquake-resistance measures. Taking the designs of gravelly soil core wall rockfill dams in Changheba and Shuangjiangkou hydropower stations as study cases, above key issues are discussed herein based on current basic seismic research methods and key technologies for core rockfill dam.
