武隆接龙水库面板堆石坝填筑碾压参数的合理选择

在面板堆石坝施工中,堆石体填筑是影响施工进度、质量和投资的主要因素,通过现场碾压试验合理确定填筑参数既是施工规范的要求,更是坝体填筑之必须。通过施工机械和填料级配的选择、加水量试验、填料层厚试验、碾压遍数试验、干密度试验等,经综合分析,从而合理确定填筑碾压参数,使坝体填筑的各项指标满足设计要求。

Reasonable Selection of Filling and Rolling Parameters for the Face Rockfill Dam of JieLong Reservoir in WuLong

In the construction of face rockfill dam,the filling of prepacked rocks is the main factor effecting the construction progress,quality and cost.Reasonably determining the filling and rolling parameters through in-site rolling experiments is not only the requirement of construction code,but also the demand of dam filling.Through construction machinery and filling materials selection,water content test,filling layer thickness test,rolling number test and dry density test,the filling and rolling parameters can be determined to meet the design requirement.
