三峡工程明渠截流难度影响因素及其改善措施

Research on affecting factors of closure difficulties and engineering measures for TGP's 3rd-stage open channel closure

根据三峡工程三期截流综合难度指标 ,分析了三期截流难度的影响因素 ,并就减轻截流难度的工程技术措施进行了初步研究 ,提出了具体意见 。

It is considered that the comprehensive difficulties of open channel closure work will be the largest one in the world. The affecting factors of the closure difficulties are analysed, a primary study on the engineering measures to decrease the closure difficulties is made and a recommended scheme put forward.
