绿竹坝水库工程砼面板堆石坝分区料现场碾压试验分析

Compacting Test Analysis of Concrete Face Rock- Fill Dam in Lüzhuba Reservoir Project

为了获得满足设计指标和施工工艺要求的最优施工碾压组合和碾压参数,结合工程特性对绿竹坝水库大坝填筑材料参数进行碾压试验分析。现场碾压试验确定了合理的铺料层厚、碾压遍数、行走速度和加水量等施工参数。试验结果表明:坝料设计填筑标准和碾压施工参数与工程特性匹配性较好,为后期大坝填筑提供了重要的技术指导依据。

In order to obtain the optimal combination and parameters of construction compaction which can meet the design and construction technology requirements, combined with the engineering characteristics, the compacting test analysis for filling material parameters of Lvzhuba reservoir dam has been done. The rational paving layer thickness, compaction times, walking speed, water addition amount and other parameters have been determined by the field compaction test. The test results show that： the dam material filling design standards and construction compaction parameters have good matching with the engineering characteristics, which can be provided as an important technical guidance during the dam filling construction.
