【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 analyze the influence of discharge of Wujiangdu Hydropower Station on the navigable flow conditions of the downstream Wujiangdu wharf, a two-dimensional unsteady flow mathematical model of Wujiangdu wharf is established, and the model is verified by using the measured water level and velocity data. Simulation and analysis of constant circulation conditions are carried out. In view of the representative mode of power generation discharge, the variation of flow velocity and specific drop duration of 10 min water level is adopted to analyze the hydrodynamic change process of Wujiangdu reach caused by the discharge of power station. Combined with ship uplink capacity, the influence of power station discharge on ship berthing is analyzed.
