| 摘 要： | 通过对挖入式港池的试验研究,归纳总结回流横轴断面上影响垂线平均流速的因素,表明流速横向分布规律服从二次曲线分布;提出回流横轴断面上垂向流速分布沿横向位置从回流流入部分到回流流出部分从二次曲线分布渐变为直线分布的规律。

| Abstract: | According to the experimental research in dug-into basin,the factors are summed up which affect the average vertical velocity of circulating flow cross section,which indicates the distribution routine of velocity in horizontal directions similar to conic section.It is suggested that velocity distribution in vertical directions gradually changes from conic section to straight line,from inflow part to outflow part. |

| Keywords: | dug-into basin average vertical velocity velocity distribution in horizontal vertical directions velocity distribution in vertical directions |
