| Abstract: | The research results of the key techniques for roller compacted concrete(RCC) cofferdam construction of the Three Gorges Project(TGP) are presented in this paper.The RCC cofferdam construction of TGP was featuring tight schedule,high intensity and strict technical requirements.By means of full face spreading roller compaction,the RCC cofferdam grew up in a continuous manner with a number of records in the history of RCC construction,such as monthly pouring record of 476,000m 3,daily record of 21,000m 3 and hourly record of 1,265m 3.The research result of RCC cofferdam construction of TGP may be available for the references to other similar projects. |
