新疆卡拉贝利水库泥沙二维数学模型坝前冲刷计算初探研究

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,库区仍淤积严重。结合实际工程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,构造出新疆卡拉贝利水库泥沙淤积二维数学模型,运用该模型对卡拉贝利水库进行坝前冲刷计算初探研究,并进行了模型验证,以达到模拟水库泥沙淤积的目的。

Research on Calculating Xinjiang Ka-La-Bei-Li Reservoir Sediment Erosion Front by Using the Two-dimensional Mathematical Model

Reservoir in South Xinjiang database as a result of the early running,storage capacity rapid siltation loss,although it has changed the way,siltation in the reservoir area is still serious.In this paper,the flow equation of motion,and the amendment of the sediment movement equation based on the available data at the same time in line with the introduction of water ADPL sand,and bed resistance,such as sediment gradation formula as a supplement equation,constructed in Southern Xinjiang Ka-La-Bei-Li Reservoir ...
