摘　　要：根据南通市狼山水厂扩建工程所在地的地质条件及周围环境的特殊要求,提出了一种长江水下隧洞式取水头部的设计方案,其中取水口采用浮运双壁钢沉井围堰进行施工、水下隧洞采用新奥法结合传统支护法进行施工。工程实践表明,该设计方案经济合理、施工安全可靠。According to the geologic condition and the special requirement of environment in the area of the extension project of Langshan Waterworks in Nantong, a tunnel-type underwater intake header in Yangtze River was designed. The inlet of the water intake header was built within a double wall steel caisson cofferdam which was moved to the site by a ship, and the underwater tunnel was built by means of New Austrian Tunneling Method （NATM） combined with traditional supporting method. The practice of the project shows that the design is reasonable and economical, and the construction method is safe and reliable.
