摘　　要：泾河东庄水库是拟建在典型的高含沙河流上的水利枢纽。本文运用河工动床模型相似理论和异重流运动相似条件的最新研究成果进行了模型设计和制作 ,并进行了典型组次的排沙试验 ,研究不同水沙条件、河床边界条件及库区蓄水条件下的排沙情况 ,得出了排沙比及排沙量与进出库流量、沙量。Using the latest developed laws of similarity of moveable bed model and the similarity conditions of density current,the model to simulate the sediment flushing processes of the Dongzhuang reservoir is presented in this paper.Based on the model,the typical runs of sediment flushing experiment were carried out and the relationship between the sediment delivery ratio and the sediment flushing quantity,the sediment concentration of input and output flow of the reservoir and the initial conditions of water level were revealed.
