摘　　要：杭州八堡排水泵站为扩大杭嘉湖南排重大水利工程,也是京杭运河沟通钱塘江第二通道的关键性节点工程,设计排涝流量200 m^3/s,为大(1)型排涝泵站。由于泵站进水口与八堡船闸引航道交汇布置,泵站运行对进水口附近通航水流条件及航道冲刷产生影响。通过建立泵站及泵前航道平面二维数学模型,计算分析了泵站不同运行工况下进水口附近流速流态分布情况,提出了满足泵前航道安全的调度运行方式。Hangzhou Babao Drainage Pump Station with large drainage is the important hydraulic engineering of Expanded Hangjiahu Nanpai.The design drainage discharge is 200 m^3/s,it is also the key project of the second channel connecting Beijing-Hangzhou Canal and Qiantang River.When the pump station is running,it influences the navigation flow condition and water-way erosion,because of the confluence of lock approach and the pump intakes.Based on the two-dimensional numerical model of the pump station and water-way near the pump,the velocity distribution near the pump intakes under different operating conditions is analyzed,and the operation scheme for the safety of water-way near the pump is proposed.
