摘　　要：作为当今最大的水利工程,三峡工程在施工期的1999~2001年三年间,混凝土年浇筑强度均在400万m^3以上,其中2000年达548万m^3,创造了世界纪录.本文概述了三峡工程大体积混凝土施工中的主要技术难题,评述了大体积混凝土施工的主要特点,系统地探讨了工程快速施工中应用的各项关键技术,并列举了关键技术指标.三峡工程施工实践表明,材料制备、温控防裂技术、施工工艺三方面的技术创新保障,可较好地满足施工进度及质量要求.Serving as the largest water conservancy project nowadays, Three Gorges Project faced severe challenges during the construction period. The annual average concrete placement intensity was beyond four million cubic meters between 1999 and 2001. Especially, in 2000, the concrete pouring intensity had reached 5.48 million cubic meters. Based on a briefly review of the main difficulty and construction characteristics of Three Gorges Project, this work discusses the new technologies applied in the rapid construction of the engineering and listsout some keytechnical indicators. The engineering practice of Three Gorges Project indicated that technological innovation of material preparation, crack control technology, and quickconstruction technology can meet the requirements of construction schedule and quality.
