通过分析河型相同的山东黄河河道以及黄河支流渭河、北洛河高含沙洪水的输沙特性,同时考虑到含沙浓度增加将使粗颗粒的沉速大幅度降低与为了保持流动的稳定性控制高含沙水流不进入层流所需的水流条件,得出如下结论:山东河道在流量4000~5000米~3/秒,可顺利输送含沙量400~900公斤/米~3的高含沙水流入海,充分利用山东河道存在着的巨大输沙潜力,是解决黄河下游泥沙问题的方向。
By analyzing the characteristics of sediment transport in the Yellow River and the Yellow River tributaries of the Weihe and Beiluohe high sediment floods, taking into account the increase of sediment concentration will greatly reduce the sedimentation rate of coarse particles and in order to maintain the stability of the flow Controlling the flow conditions of the high-sediment-laden flow that do not enter the laminar flow, the following conclusions are drawn: At a flow rate of 4000-5000 m -3 / s in Shandong rivers, it can smoothly transport high-level sediments with a sediment concentration of 400-900 kg / m 3 Silt water flows into the sea and makes full use of the huge potential for sediment transport in the rivers in Shandong Province, which is the direction to solve the sediment problem in the lower Yellow River.
