摘要
对根据输沙平衡原理及冲止流速概念建立的一般冲刷公式(2)和公式(1)进行了介绍,利用一维恒定饱和输沙模型,对压缩河道的河床冲刷进行了数值计算并得出冲刷规律,以推广输沙模型的应用。
The following paper introduces the general flushing formula (1) and (2) set by the principle of sediment transport equilibrium and the definition of velocity for erosion control, and carries out numerical calculation on river bed flushing of compressed river way by using one-dimensional steady saturation sediment transport model and gets flushing rule, in order to popularize the application of sediment transport model.
