弧线导航墙改善船闸引航道口门区水流状态试验

Experimental study on improvement of flow regime by arc navigation wall at the entrance area of shiplock approach channel

对弯曲河道船闸下游的引航道设计形式进行试验研究,提出引航道采用弧线型设计较之直线型设计能有效减小口门区横向流速、纵向流速,改善水流状态。并讨论了弧形导航墙张角的大小和弧度的大小对下游口门区水流状态的影响。

By experimental study on some different forms of navigation walls of shiplock at the serpentine channel,it is shown that adopting arc navigation wall at the entrance area of ship lock approach channel can reduce the transverse and longitudinal velocity of flow at the entrance area of shiplock approach channel and improve the flow pattern.The effect of the inclination angle and curvature of the navigation wall on the flow pattern at the downstream entrance area is also analyzed.
