摘　　要：《三峡工程坝体混凝土快速施工技术研究》是国家在“七五”期的重点科技攻关课题 ,其后经过“八五”、“九五”期间的进一步攻关及工程实践 ,又相应取得了一系列重大成果。文中简要介绍的三峡大坝混凝土快速施工方案及工艺特点、人工砂石料特高强度生产技术、混凝土生产系统及二次风冷技术、混凝土原材料的优选与配合比优化 ,以及大坝混凝土温控防裂技术等 ,不仅反映了上述科技攻关与生产实践的重大成果 。禩echnology about concrete rapid construction for dam body of Three Gorge Project》was one of main scientific and technical questions fro researching during the five years from 1986 to 1990, it was applied in engineering practice and improved during the ten years from 1991 to 2000, some important results were obtained. The paper introduces the construction scheme of concrete construction for dam body of Three Gorge Project, its process features, production technology of artificial aggregate in super high intensity, production system of concrete & double air cooling technology, optimization of concrete materials & mix proportion, anti checking technology through temperature control in constructing dam concrete. Above technologies not only are the important results of researching and production practice, but image present advanced technology of dam concrete construction in China.
