| 摘 要： | 高土石坝需要进行极限抗震能力和地震破坏模式分析。通过坝体动力反应分析、动强度验算以及地震变形分析，综合研究了高心墙土石坝的破坏过程。认为处于抗震极限状态的大坝防渗体及上游反滤料的顶部存在动强度不足问题，进而引起坝顶地震裂缝及上游反滤料顶部液化，最终导致坝体上、下游坝坡的失稳破坏

| Abstract: | It is crucial to analyze the limit aseismic capacity and the failure mode for high core rockfill dam.The process of failure for high core rockfill dam is comprehensively studied on the basis of analyzing dynamic response,dynamic strength and seismic permanent deformation.The dynamic strength appears to be severely deficient in the impervious body and the upstream filter layer as the dam falls into the limit state.It is considered that the deficiency of dynamic strength will induce seismic fracture and lique... |
