摘　　要：以深圳市沙井排水泵站为例,采用三维模拟软件CFD对泵站前池整流进行了数值模拟及水力优化,并利用物理模型试验进行了验证。结果表明,在一定水力损失范围内,前池的配水渠段加设挡水堰并进行改进后,能明显改善水流流态,有助于减弱甚至消除侧向斜交水流惯性作用产生的偏流现象,可为泵站侧向斜交进水方式的研究提供参考。Taking Shajing drainage pumping station in Shenzhen City for an example, three-dimensional software CFD is adopted to simulate forebay rectifier and hydraulic optimization of pumping station. And it is verified by physical model test. The results show that within a certain hydraulic losses range, flow regime can be significantly improved by adding the water retaining weir to forebay distributary, which is helpful to abate or even eliminate oblique flow inertial effects of lateral deviation. Thus, it provides reference for study of lateral oblique inlet way of pumping station.
