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。
water jets have been widely used as a normal measure in dredging engineering. The result of an ex-perimental 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 is presented, particularly the development of scour within short time is shown, finally a semi-em-pirical formula is gotten.
