摘要
采用正交曲线坐标系下的河道平面二维数学模型 ,研究了嘉陵江何家碛边滩采砂后河道流势、流态、滩槽流速、主流位置、水面高程及比降的变化规律 ,预测了采砂方案完成后卵石推移质输沙率变化及其对航道的影响 。
Variations of flow pattern,flow velocity in deep pool and side bar,mainstream thread,and water surface,caused by excavation project,are investigated by two dimensional mathematical model in an orthogonal curvilinear coordinate system.The change of bed load transport rate,and redeposition rate are predicted.The influences of the excavation project on navigation are analyzed.Grid type and flat type excavation alternatives are proposed and discussed.
