黑岗口水库水沙特性的数值模拟

小浪底电站建成后,作为开封市水源地的黑岗口水库不再进行排沙,为了研究黑岗口水库的多年的水沙沉积及分布问题,通过对花园口水文站观测数据及黑岗口引流量数据的分析,结合黑岗口地形数据,依据插值和拟合数学理论,利用Flow-3D软件进行建模并进行数值计算得到水库泥沙的空间分布,并推导预测黑岗口水库未来的水沙分布及趋势分析,对黑岗口水库的管理及优化引水工作方式等提供依据,具有一定的现实意义。

Numerical Simulation of Flow and Sediment Characteristics in Heigangkou Reservoir

After the completion of Xiaolangdi hydropower station ,as the water source of Kaifeng city ,Heigangkou reser-voir no longer carried out desilting .In order to study the water and sediment deposition and distribution in the Heigangk-ou reservoir ,based on the observation data of Huayuankou hydrological station and the data of Heigangkou drainage data , combined with the data of Heigangkou mouth terrain ,based on the interpolation and fitting mathematical theory ,this pa-per adopted Flow-3D software to model and calculate the reservoir spatial distribution of reservoir sediment .The distri-bution and trend of water and sediment in the future of Heigangkou reservoir was analyzed .This is the basis for the man-agement of the Heigangkou reservoir and the way of optimizing the way of water diversion ,and it has certain practical sig-nificance .
