摘　　要：论述长洲水利枢纽一期工程的导流标准、导流方案、导流建筑物布置和设计等。指出采用一期导流建筑物全年不过水土石围堰方案,既简化了施工程序、确保围堰在一个枯水期内形成,又充分利用了外江台地船闸大量的开挖弃土,大大降低工程投资。一期围堰经受住西江100年一遇超标洪水考验,实践证明该方案是经济、合理、可靠的。The paper disserts the diversion standard, the diversion scheme, the layout and design of diversion structures etc. of the first-phase construction of Changzhou Hydropower Complex; presents that the scheme of all the year non-overflow earth and rock cofferdam is adopted for the first-phase diversion structures, which not only simplify the construction procedure and ensure the cofferdam is formed during one low flow period, but also a large amount of excavation waste of outer river terrace ship lock is made full use of so as to greatly reduce the project investment. It is proved that the scheme is economical, reasonable and reliable by the first-phase cofferdam standing up to the Xijiang hundred-year over-standard flood.
