摘　　要：钱塘江向来以水文及地质条件复杂著称。以三堡一线船闸上游靠船墙改造工程实例,对钱塘江直立式围堰及井点设计与计算进行了总结与探讨。阐述了工程的重点与难点。介绍了围堰方案比选和施工方法。着重介绍了井点排水设计与施工方法。可供参考。The Qiantangjiang River is famous for its complicated hydrology and geological condition. Taking the reform engineering of berthing wall of Sanbao line navigation lock as an example, this paper has made a sum and discussion on the design and calculation of vertical cofferdam and well point in the Qiantangjiang River. It states the key points and the difficulty of the engineering. Then it introduces the plans comparision and contructive method of the engineering. Emphatically it introduces the design of well point drainage and its constructive method, which could be referenced.
