长河坝水电站大坝砾石土心墙填筑质量控制

摘要

结合长河坝水电站大坝心墙砾石土防渗料填筑，围绕如何快速检测以满足施工进度要求，通过系列比较试验研究，提出了一种砾石土填筑压实质量控制的快速检测方法，可大幅缩短检测时间以满足高强度大方量填筑质量检测控制要求。同时对前期砾石土心墙填筑质量进行了分析评价，指出了存在的问题。%Based on the placement of the dam core wall gravel soil impervious material of Changheba hydropower station and on trying to conduct a rapid test to meet the construction schedule, the paper puts forward a rapid test method of gravel soil embankment compaction quality control after a series of comparisons, tests and study. It could signifi cantly shorten test time to meet the intensive and massive gravel soil placement quality control requirements. Meanwhile, the quality of the early stage gravel soil core wall placement was analyzed and evaluated, and the existing problems were pointed out.
