摘要
利用等时段的特征线法数值模拟三峡永久船闸输水系统不补水工况下的输水特性 ,得出了输水管道沿程各节点水头及流量的变化规律 .计算结果与物模成果吻合良好 ,充分证明了该方法在船闸输水特性的模拟中具有较高的精度和可靠性 .成果可作为制定船闸运行方案的依据 .
The characteristic line method is used to simulate the characteristics of the water conveyance system of the ship lock in the Three-Gorges Project. The unsteady variation processes of water head and discharge are obtained. The calculated results are in good agreement with experimental results, providing a basis for determination of schemes of ship lock operation.
