摘要
采用准二维数学模型,研究了嘉陵江北碚防洪堤工程修建后河道水流条件变化及其对通航、上游防洪等的影响,分析了工程后,水面及比降变化、主流速度变化和上水航线流速变化。
Variations of flow condition and their influences on navigation and flood control,caused by the flood embankment in Beibei reach of the Jialing river,are investigated by means of quasi two dimensional numerical model. Changes in water surface & its gradient,flow velocity in mainstream thread,and flow velocity in upbound sailing line are analysed.A reasonable and feasible project alternative are proposed.
