基于下游引航道口门区流态的隔流墙结构形式优化措施

based on flow pattern at entrance area of downstream

船闸外侧水流受枢纽下泄不稳定流的影响较大,为解决流速、流态对船舶航行的不利影响,维持引航道水流条件,分析下游引航道不稳定水流的成因,结合近年来建成的隔流墙布置方式和结构形式,通过平面布置、模型试验、资料统计分析等方法,探讨了实体墙、隔流墩、透水孔墙等诸多结构形式对水流条件的影响,研究提出多种引航道隔流墙结构布置形式和优化措施方案。

The water flow outside the ship lock is greatly affected by the unstable flow discharged from the hub.To address the adverse effects of flow velocity and flow patterns on ship navigation and maintain the flow conditions of the approach channel,this article analyzes the causes of unstable water flow in the downstream approach channel,combined with the layout and structural types of the diaphragm wall built in recent years.Through methods such as plane layout,model testing,and data statistical analysis,the impact of various structural forms such as solid wall,barrier pier and permeable hole walls on water flow conditions has been explored.Multiple types of approach channel flow separation wall structural arrangements and optimization measures are proposed.
