| 摘 要： | 射流冲刷作为常用的清淤手段被广泛应用于疏浚等方面的工程实践。针对粗沙沙床条件下某靶距二维垂向淹没射流冲坑深度进行研究,观测动态冲坑深度随时间的发展,尤其关注动态冲坑深度在很短时间内发展规律,并探索射流速度对动态沙坑深度的影响,得出冲坑深度的经验公式。

| Abstract: | water jets have been widely used as a normal measure in dredging engineering. This paper presents the result of an experimental study of the erosion of sand bed by impinging vertical plane jets at a height in order to explore the depth of the scour hole, particularly shows the development of scour within short time,finally get a semi-empirical formula. |

| Keywords: | jets vertical erosion experiment dredging engineering |
