摘　　要：文章结合现有截流施工技术和拉贝利大坝三期截流实际施工条件,对卡拉贝利大坝三期截流施工方案进行了设计。通过计算,明确了截流时段和截流流量,并通过综合比较各截流方案施工规划及主要技术经济指标,提出了戗堤轴线沿一期纵向围堰至明渠进口截流的方案。文章还给出了截流戗堤断面结构形式,明确了龙口分区,最后提出了龙口护底加糙混凝土桩这一加糙措施。According to the practical construction condition of the third-phase river closure project of Kalabeili dam and the existent river closure construction technique, the third-phase river closure scheme for Kalabeili dam is designed. Through the calculation,the period and discharge of the river closure are determined. The paper provides the river closure scheme with the closure dike axis along the first period longitudinal cofferdam to the intake of the open channel by the comprehensive comparison for the construction plans and major technical and economic indicators of the river closure scheme. The paper also gives the section structure type of the closure dike, determines the zones of closure gap and provides the roughening measure of bed protection for closure gap with concrete pile.
