摘　　要：八堡排水泵站利用运河二通道作为排水干河,进水口附近的水流流态较为复杂。通过平面二维数学模型结合水工物理模型,对泵站进水口不同布置方案时的进流流态及通航水流条件进行研究。对进水口口门宽度、导航墩角度及单孔净宽等多因素指标进行分析,提出八堡泵站进水口推荐布置方案。该方案可同时满足泵站进流流态及运河二通道通航安全要求。Babao Drainage Pump Station uses the Grand Canal Second Passage as the drainage main river,and the flow pattern near the intake is complex.Based on the plane two-dimensional mathematical model and the hydraulic physical model,the inlet flow pattern and navigable flow conditions of the pump station intake with different layout schemes are studied.Based on the analysis of the gate width of the intake,the angle of the navigation pier and the clear width of the single hole,the recommended layout of the intake of Babao pump station is put forward.The scheme can meet the requirements of the flow pattern of the pump station and the navigation safety of the second passage of the canal at the same time.
