摘要: 利用一维数学模型计算万州至涪陵河段通航水流条件(水深、流速、比降),并对各蓄水阶段通航水流条件变 化情况进行对比分析。研究结果表明:万州至涪陵河段航道均不同程度的受到蓄水影响,并相应产生一定变化,有 利有弊。蓄水期水位抬高,流速减缓,对航道有利但也造成部分滩险的泥沙淤积。

Abstract: To study the changes of channel conditions and trends of the reach from Wanzhou to Fuling in the Yangtze River since the Gorges Reservoir begins to impound,various kinds of water level and water flow rate data are respectively collected from each hydrometric station in various periods of water storage. One-dimensional mathematical model is adopted to calculate the navigation flow condition ( water depth,the flow speed,slope) from Wanzhou to Fuling and comparatively analyze the changes of navigation flow condition on each storage period. When the water level is increased in the water storage period, the velocity of water flow decreases at the same time,which is good for the channels. However,it also leads to sediment accumulation at some reaches.
