摘　　要：青草沙水源地原水工程是一项大规模的原水输水系统，南汇支线工程是其子项之一。它包括一座88万m^3／d增压泵站和总长约90km的输水管线，输水管口径为DN2000-DN1000。在设计南汇支线增压泵站过程中，主要从系统方案、水泵出水管阀门设置、水泵调节方案、水泵变频台数确定、泵站水锤分析等方面进行优化设计，使整个系统技术和经济更合理，并在工程中采用计算机技术进行模拟研究，为工程的优化设计和日后的运行管理提供参考。The Raw Water Project at Qingcaosha Water Source is a huge convey system of raw water, and Nanhui Branch Works is a component, covering a lift pumping station of 880 000 m3/d and the water conveyer of about 90 km in total length, DN2000～DN1000 in diameter. The design of the lift pumping station on Nanhui Branch Works is optimized generally in the proposed system, valve fixed at the pump outlet, proposed adjustment of pumps, determination of the number of variable frequency pumps and analysis of the water hammer of the station, making the whole system more rational technically and economically. Simulation study is done with the computer which is a good reference for optimized design and operation management.
