高温多雨地区碾压混凝土施工--柬埔寨额勒赛下电站大坝碾压混凝土施工技术综述

摘要

With a case study of the Cambodian Lower Stung Russei Chrum Hydropower Station, the construction technol-ogy of the roller compacted concrete in high temperature and rainy area is introduced, including the mixing proportion optimization of concrete raw materials, determination of the construction parameters, concrete spreading and division of placing areas, and measures for temperature and rainfall controlling.Normal operation of the dam since the impounding of the reservoir shows that the construction technology is satisfactory.%针对柬埔寨高温、多雨、蒸发量大的气候特点，介绍了额勒赛下电站大坝碾压混凝土的施工技术，包括混凝土原材料的配合比优化、施工工艺参数的确定、混凝土摊铺及仓位划分、温控和雨控措施等。水库建成蓄水至正常水位后，大坝运行正常，表明所用技术措施是正确的。
