| 中文摘要: |
| 通过修正泥沙运动基本方程，并采用水流挟沙力、河床糙率、异重流计算等方面的最新研究成果，建立起高含沙水库泥沙数学模型。通过选择黄河三门峡水库及巴家嘴水库的泥沙观测资料进行仿真计算，证明了所建模型的可靠性。并应用该数学模型模拟泾河东庄水库泥沙淤积及排沙规律，取得了与泥沙模型试验结果相接近的计算成果，表明该模型具有模拟高含沙水流运动、溯源冲刷、泥沙级配变化、异重流运动等功能。 |
| 英文摘要: |
| Based on the modified movement equation for sediment and new findings of sediment transport capacity,riverbed roughness as well as density flow,a quasi 2 D mathematical model for movement of high concentrated sediment in reservior is established.The validity of this model is verified by field observation data from Sanmenxia Reservoir and Bajiazui Reservoir.The model is applied to forecast the deposition and sluice effect of Dongzhuang Reservoir,Jing River。The computational result is in good agreement with the physical model data. |
