黄河下游河湾平面参数特性及其实验研究

以黄河下游,尤其是游荡型河段的研究资料为背景,通过模型试验,在分析河势变化过程的基础上,运用数学统计与理论探讨,研究了不同水沙条件下河湾中心角、河湾半径和河湾跨度的变化趋势,初步揭示了随水沙、比降条件的改变,河势的变化过程,总结出河流在边界条件改变后河势演变的特点,对预测河道演变趋势,有效地河道整治具有一定的意义。

The Characteristics of the horizontal parameters downstream bend of Huang River and Experimental Study

Based on the information of the Huang River,especially the wandering segment,through the model test,this paper researched the change of the span,radius and central angle of the bend,with mathematical statistics and theory discussion,under different water and settlement,it initially revealed the river evolution processing with the change of water and sediment,and summed up the river characteristics after the change in boundary conditions.It has certain significance for river regulation and the evolution of r...
