【摘要】：為分析烏江渡水電站泄流對(duì)下游烏江渡碼頭通航水流條件的影響,建立了烏江渡碼頭河段二維非恒定流水流數(shù)學(xué)模型,并運(yùn)用實(shí)測水位流速資料對(duì)模型進(jìn)行驗(yàn)證。對(duì)恒定流通航條件進(jìn)行模擬分析。針對(duì)電站發(fā)電泄流代表方式,采用流速和比降歷時(shí)變化、10 min水位變率,分析電站泄流引起的烏江渡河段通航水動(dòng)力變化過程。結(jié)合船舶上行能力,分析電站泄流對(duì)船舶進(jìn)港靠泊的影響。
[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.
