摘　　要：采用三维紊流数值模拟方法对多机组泵站进水池的流态进行分析研究,并在此基础上进行优化水力设计.数值模拟结果表明多机组泵站位于进水设施两翼的进水池大多为偏流进水,在多机组泵站进水设计中采用蜗形进水池,前池采取一定整流措施,可以改善进水池内的流态.Three-dimenslonal simulation is adopted to investigate hydraulics characteristics for intake sumps of multi-unit pumping station. Based on this, optimum hydraulic design of intake sumps is conducted. The results of the numerical simulation shnw that bias flow is brought in rectangle intake sumps on the side of multi-unit pumping station. And flow distribution in intake sumps is improved by commutating method of forebay of pump stations.
