摘　　要：为探讨八堡排水泵站工程建设后的工程影响,建立了工程区域河段的二维水动力及泥沙数学模型,并在模型验证的基础上,对泵站建设进行了水流条件及冲淤变化数值模拟。结果表明:八堡排水泵站建设完成后工程河段的流场变化仅局限于泵站工程附近小范围水域,洪水期间排涝部分区域流速增加。经历一个典型洪水过程后,八堡排水泵站泄洪排涝口门区泥沙冲刷量最大达2.4万m^3,可有利于缓解船闸口门区淤积。In order to explore the engineering impact of Babao Pumping Station,a two-dimensional hydrodynamic and sediment mathematical model was established.Based on the model verification,numerical simulation study about the water flow conditions and change of erosion and deposition was carried out.The results show that the flow field change of the engineering section after the completion of Babao Pumping Station is limited to a small area of water near the pumping station,and the flow rate of the drainage area increases during the flood period.After a typical flood,the maximum erosion quantity at the entrance area of Babao Drainage Pumping Stations is 24000 cubic metre,which may help alleviate the siltation at gate area.
