摘要
南水北调PCCP管道工程管道是世界上迄今为止最大的预应力钢筒混凝土管道（PccP），对特大型PccP管道沟槽的回填无经验借鉴，在长期的施工中探索出一项紧密的回填技术控制，适用特大型PCCP管道工程沟槽范围内土石方填筑。
Abstract
The pipeline of South-To-North Water Diversion PCCP Pipeline Project is the biggest PCCP in the world until now. There are not experiences about the oversize PCCP pipeline groove backfrll. The compact groove backfill technique from the long-time construction research is applicable to the earthwork and stonework filling within the scope of oversize PCCP pipeline project.
