摘要:
桃花江旅游景观船闸在布置上因受到枢纽地形与河道防洪的限制,难以满足规范要求.采用几何比尺为1∶25的整体水工模型进行了试验研究,2座枢纽的控制运行条件均为最高通航水位组合,主河道中流速较大,特别是上下游口门处引航道的横向流速较大,不能满足规范要求.修改方案主要通过减小2座船闸上下游引航道与桃花江主河道夹角,并对口门附近地形进行了相应的疏浚.试验结果表明,修改方案有效降低了2座船闸上游口门处横向流速等不利因素.

Abstract:
Taohuajiang shiplock aims at tourist travel.It is hard to satisfy the national navigation norm due to being subjected to restriction of the geography and river flood control.A 1∶25 hydraulic model is adopted for the research.The research results show that the control condition of two shiplocks is the highest navigable stage.At this time,the flow velocity is large,especially the horizontal current velocity near the entrance area of the approach channel.It dissatisfies the norm requiremnts for ships and brings about an insecurity factor.The modified scheme is to decrease the angle between the upstream and downstream approach channels and Taohuajiang main course,and to dredge the entrance of the approach channel of the shiplock.Experiment results of the modified scheme show that horizontal current velocities near the upper entrance areas of the two shiplocks has been improved substantially.
Key words:  Taohuajiang River  navigation project  hydraulic model test  entrance of the ship approach channel lock  rubber dam
