三峡工程碾压混凝土围堰施工若干重大技术问题研究
|
摘要
本文系统地介绍了三峡工程中的关键项目之一碾压混凝土围堰施工过程中若干重大技术问题的研究成果。这一项目工期紧、施工强度大、技术要求高 ,施工采用全断面摊铺碾压、不间断连续上升方式 ,创造了最高月强度 47 6万m3,最高日强度 2 1万m3,最高小时强度达到 12 65m3等多项碾压混凝土施工史上的新纪录。本文的研究成果对其它类似工程的实施有一定的借鉴作用
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.
