土石坝填筑砂砾料碾压试验分析

Analysis of Compaction Test of the Earth-rockfill Dam Filling Sandy Gravel

在洋河水库除险加固工程中,砂砾料是大坝(土石坝)填筑料的主要材料,为了确定砂砾料在筑坝过程中的压实质量控制指标,使压实效果达到设计要求,进行了砂砾料的现场碾压试验,确定了现场施工设备条件下,砂砾料的铺土厚度、碾压遍数及加水量等碾压技术参数。

Sandy gravel is the main material of dam （ earth-rockfill dam） filling material in the danger-eliminating and reinforcing project of Yanghe reservoir. In order to determine the sandy gravel in control index of compaction quality in the process of dam which effect to meet the design requirements, the author had a gravel field rolling test of material, studied the thickness of the sandy gravel, compaction times ,water addition and so on under the condition of the site construction equipment.
