摘　　要：进水前池是连接泵站与河道的建筑物,不良前池流态会给泵站的稳定运行造成严重影响。此次研究以某排灌站为例,利用PIV模型试验的方式,探讨了底坎对侧向进水池前池流态的整流效果的影响。结果显示,设置底坎可以获得显著的整流效果,且底坎断面为梯形、高和底宽分别为池深的0.5倍和0.3倍,与进水池的距离为水泵叶轮直径的10倍时整流效果最佳,可以为工程建设的顺利进行以及相关类似研究提供支持和借鉴。The intake forebay is a building connecting the pump station and the river.The bad flow pattern of the forebay will seriously affect the stable operation of the pump station.In this study,taking a drainage and irrigation station as an example,the influence of the bottom sill on the rectification effect of the flow pattern in the forebay of the side inlet pool is discussed by means of PIV model test.The results show that the setting of the bottom sill can obtain significant rectification effect,and the cross section of the bottom sill is trapezoidal,the height and the bottom width are 0.5 times and 0.3 times of the pool depth respectively.When the distance from the bottom sill to the water inlet pool is 10 times of the pump impeller diameter,the rectification effect is the best,which can provide support and reference for the smooth construction of the project and related similar research.
