摘　　要：针对三峡—枝城河道的地形特征 ,建立一维不稳定流模型。在三峡电站预先给定的航运约束和流量过程下 ,研究电站下游的不稳定流动对航运的影响 ,从而为获得实际可行的三峡泄流量提供一种途径。A one-dimensional unsteady flow model is established based on the topography of the river course between the Three Gorges and Zhicheng. The navigation restrictions and the designed flow process of the Three Gorges hydropower station given, the influence of the downstream unsteady flow on navigation is studied, and a method for gaining a practical flow of the Three Gorges hydropower station for satisfying the navigation demand is presented.
