本文基于理论和试验研究,导出在平衡条件下二维余波中悬移质含沙量的垂向分布公式。研究结果表明,在实践中可能有以下三种情况:(1)含沙量在水面附近较低,中部较高,近底部更高;(2)含沙量在水面附近较高,中部较低,近底部最低;(3)含沙量在水面附近较高,中部较低,近底部又高。 文中最后提出并讨论了泥沙在波浪作用中的一种“冲泻质(Wash Load)”新概念。
Based on theoretical and experimental studies, this paper derives the vertical distribution formula of suspended sediment concentration in two-dimensional after-wave under equilibrium conditions. The results show that in practice, there may be the following three situations: (1) the sediment concentration is lower near the water surface, higher in the middle and higher in the bottom; (2) the sediment concentration is higher near the water surface and lower in the middle , Near the bottom of the lowest; (3) sediment concentration in the vicinity of the water higher, lower central, near the bottom and high. Finally, a new concept of “Wash Load” is proposed and discussed in the paper.
