| 摘 要： | 研究了沙质河床清水冲刷粗化机理，即它不是靠推移质冲刷，而主要是靠悬移质冲刷，在粗化过程中产生沙波，形成与水和条件相适应的稳定的沙波运动，建立新的平衡。据此，提出了河质河床粗化物理模式和计算方法。

| Abstract: | In this paper, a physical model on the armoring of sand bed material is presented according to its mechanics, of which shows that the armoring of sand bed material is due to scouring of suspended sediment rather than scouring of bed-load sediment. In the process of armoring of sand bed material the sand waves occur, and the steady sand waves which is suited to the flowing intensity are formed by scouring of suspended sediment, and a new balance state between the flowing intensity and the bed is estatilished. On the basis of this, the calculating method is given by a example. |
