摘要
基于模型试验 ,作者研究和探讨了海水注入点上、下游河道溯源和沿程冲刷过程及平衡比降、冲刷的效果和冲刷后水位的变化。结果表明 ,引海水冲刷黄河口 ,配合小浪底水库运用 ,能够延长河口流路的使用寿命 ,在一定程度上缓解黄河山东河道的防洪压力 。
Based on physical model, the article studies and discusses processes of the retrogressive and streamwise erosion, the corresponding equilibrium slope, scouring effects, and water level changes in the upper or down river of the imported seawater point. The experimental results demonstrate that the imported seawater combining with the operation of Xiaolangdi reservoir can extend the life span of the use of river mouth channels, alleviate the flood pressure in the Shandong reach of the lower Yellow River, and prolong the rise of riverbed.
