摘　　要：在论证几何变率影响和对模型沙特性比选基础上 ,运用黄河动床模型相似律和异重流运动相似条件的最新研究成果 ,完成了泾河东庄水库高含沙模型的设计 ;利用位于东庄水库上游水沙条件与之相近的巴家嘴水库进行了率定试验。结果表明 ,模型可较好地复演原型库区泥沙运动及其排沙规律。Based on the research on the geometry deformation and the properties of model sands, this paper finishes the design of the hyperconcentrated flood model of the Dongzhuang reservoir on the Jinghe River by using the latest results on the movable model similarity laws about the Yellow River and density currents. Then, calibration tests have been carried out by using the data of the Bajazui Reservoir on the Jinghe River, whose hydraulic and sedimentation characteristics are similar to the Dongzhuang Reservoir. It is shown that the model can well repeat the prototype sediment movement and the transport properties.
