| 摘 要： | 为分析乌江渡水电站泄流对下游乌江渡码头通航水流条件的影响,建立了乌江渡码头河段二维非恒定流水流数学模型,并运用实测水位流速资料对模型进行验证。对恒定流通航条件进行模拟分析。针对电站发电泄流代表方式,采用流速和比降历时变化、10 min水位变率,分析电站泄流引起的乌江渡河段通航水动力变化过程。结合船舶上行能力,分析电站泄流对船舶进港靠泊的影响。

| Abstract: | In order to study the influence of discharge of Wujiangdu hydropower station on navigation of Wujiangdu port,the two-dimensional unsteady flow mathematical model was established,and the model was verified with the nature water level and current.Navifation condition of steady flow was simulated and analyzed.According to unsteady flow on navigation discharges of the station,navigable hydrodynamics were studied by using velocity and river slope and water level change in 10 minutes during discharge.The influence of discharge for berthing was analyzed in the accordance with the ability of upriver ship. |

| Keywords: | mathematical model unstead flow water level change in 10 minutes |
