摘　　要：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.
