【摘要】 面板堆石坝填筑施工时碾压参数选择是否合理直接关系到大坝填筑质量的好坏、施工难度的大小以及成本投入的多少。大坝填筑施工前必须进行现场碾压试验以确定合理的碾压参数,并对设计控制标准进行复核。通过水布垭面板堆石坝现场生产性碾压试验,对各项碾压参数的试验成果进行了深入分析和研究,提出了合理的碾压参数及建议控制标准。更多还原

【Abstract】 The quality,the difficulty and the cost of roller compaction of concrete face rockfill dam(CFRD) is directly affected by the choice of roller compaction parameters,reasonable roller compaction parameters should be chosen through in-situ roller compaction test before CFRD construction,and design controlling index of compaction is checked.various results of roller compaction parameters are studied and analyzed in detail through in-situ roller compaction test of Shuibuya CFRD,reasonable roller compaction parameters and recommended controlling index is presented.更多还原
