摘　　要：新疆南疆地区水库由于建库初期蓄水运行,库容快速淤损,虽然改变了运用方式,但库区仍淤积严重。以水流运动方程及经过作者修正的泥沙运动方程为基础,同时引入与实测资料相符合的水流协沙力、动床阻力、泥沙级配等计算公式作为补充方程,构造出适合新疆南疆地区水库泥沙一维数学模型,并采用新疆乌鲁瓦提水库原型观测地形进行验证分析。结果表明,该模型能很好地模拟新疆南疆地区水库的输沙特性及河床变形规律。Due to the water storage operation in the initial period of the construction of the reservoir in the southern Xinjiang region,the storage capacity of the reservoir was rapidly degraded.Although the operation mode was changed,the reservoir area was still heavily deposited.This paper is based on the equation of flow motion and the equation of sediment motion modified by the author.At the same time,the calculation formulas of water flow co-sand force,moving bed resistance,and sediment gradation that are consistent with the measured data are introduced as supplementary equations.A one-dimensional mathematical model of reservoir sediments in Xinjiang,and a verification analysis using the prototype observation terrain of Xinjiang Uluwati Reservoir.The results show that the model can well simulate the sediment transport characteristics and riverbed deformation of reservoirs in the southern Xinjiang region.
