碾压是混凝土面板堆石坝控制施工质量的关键工序,在进行大坝大规模填筑前必须进行碾压试验。吉勒布拉克面板堆石坝地处我国北方高寒地区,坝高140.60 m,为了研究大坝填筑料在不同加水量下的碾压效果,确定经济合理的施工压实参数;验证并核实填筑料的碾压施工参数、设计填筑质量控制标准;检验所选用的碾压机械的适应性和可靠性等,在坝体填筑前对几种筑坝材料进行了现场碾压试验。
Rolling is the key process of concrete face rockfill dam construction quality control, before carrying out large-scale dam filling must be rolling test. In order to study the rolling effect of dam filling materials under different water additions and determine the economic and reasonable construction compaction parameters, the Jilu Bulak panel rockfill dam is located in the alpine region of northern China with a height of 140.60 m. The construction of the rolling compaction construction parameters, design filling quality control standards; test the selection of rolling machinery adaptability and reliability, etc., before the dam body filling several dam materials on-site rolling test.
