摘　　要：瀑布沟水电站心墙堆石坝采用砾石土心墙防渗料,为了确定心墙料达到设计填筑压实标准经济合理的施工参数,在大坝填筑前对砾石土料及其与粘土掺合料的渗透、压实特性以及坝体心墙料填筑施工质量控制的快速检测方法等进行了试验研究,针对土料特性,提出了适宜的碾压方案及质量控制的快速检测方法。Pubugou core-wall rockfill dam uses gravel soil as core wall impervious material. Experiments on permeable and compaction characteristics of gravel soil and the mixture of gravel soil with clay were conducted for determining the construction parameters, and the rapid detection method for construction quality was studied before dam filling. The threepoint compaction method with improved parabolic equation numerical solution was proposed for rapid detection of core wall construction.
