| 摘 要： | 分析扩散理论解决悬移质垂线分布存在的问题,介绍一种求悬移质绝对含沙量的计算方法,将近底含沙量选在紊流边界层的上边缘。采用二阶Stokes波理论求近底波浪水质点流速最大值及相应的振幅。利用现场测量资料证明公式的合理性,进而表明了公式所依据的基本理论的普适性。

| Abstract: | Some problems about the vertical distribution of suspended load by disperse theory are analyzed,and a method for calculating the absolute suspended concentration is presented,concentration near bottom being at the upper interface of the turbulent boundary layer.Based on the second wave theory,formula for the maximum water particles velocity and amplitude near bottom are obtained.Finally,the reasonability of the formula is verified by the observed data,and the general compatibility of the fundamental principle is proved. |
