摘　　要：结合国外某水电站工程,通过物理模型对水电站引水沉沙池的水力学特性进行试验研究,通过试验资料深入分析了沉沙池内水流的流态特征,流速分布等水力特性,并通过在沉沙池工作段首部加设整流栅,对入池水流进行调节,使沉沙池内水流流场分布均匀,使调节后的流场分布更利于泥沙的沉降,研究成果为工程设计提供了重要的技术支撑。Combing some foreign hydropower stations,through the physical model of hydropower station research on the hydraulic characteristics of hydropower diversion sediment basin.An analysis is made by the experimental data of flow pattern characteristics,velocity distribution and other hydraulic characteristics in sediment basin.And through sediment basin additional stilling rack to ad just the water flow into the pool so that the sediment basin inside the flow field is evenly distributed,so that the adjustment of the flow field distribution in favor of the sediment setting,the research provides important technical support for the engineering design.
