句容抽水蓄能电站下水库主堆石坝填料碾压试验探究

Research on compacting test of filling materials for main rockfill dam of lower reservoir at Jurong pumped storage power station

依据设计及有关规程规范,通过现场碾压试验,分析碾压遍数、颗粒级配等对填料压实密度的影响,论证附加质量法测试压实干密度的可靠性,提出符合实际情况并达到设计标准的填筑材料、碾压参数及施工工艺。

According to the design and relevant regulations and specifications,this paper analyzes the influence of compacting times and particle gradation on the compaction density of filling materials,demonstrates the reliability of additional quality method in testing the compaction dry density,and puts forward the filling materials,compacting parameters and construction technology that meet the actual situation and design standards through on-site compacting test.
