摘　　要：龙滩水电站大坝为200m级高碾压混凝土重力坝,混凝土总量约580万m3,是目前世界上在建的最高的碾压混凝土坝。大坝施工工期紧,浇筑强度高,要求全年连续施工,为确保工程质量和施工进度,必须采用先进的设备和工艺作保证。经过对多种可行的混凝土浇筑方案进行技术经济比较分析,在充分论证的基础上,选定以高速皮带机运输转塔式布料机等为主的连续运输浇筑方案,并对选定方案进行了详细的施工布置设计。该成果将在工程实施中应用。The Longtan Hydropower Station has a high RCC gravity dam with the height of over 200 m,,which includes a total concrete quantity of 5.8 million cubic meters, being the highest RCC dam under construction in the world. The dam construction is characterized by short construction period, high placing intensity and required continuous year-around construction. In order to ensure the quality and construction progress, the advanced construction equipment and workmanship must be used. On the basis of technical and economic analysis of several feasible concrete placing schemes and sufficient justfication, a continuous conveying and placing scheme with a major means of high speed belt conveyor plus tower spreader has been selected.A detailed construction layout design was done on the basis of the selected scheme. The achievement is to be implemented in the construction of the project and it will play an important role in construction of the project.
