导航堤开孔是改善口门区通航水流条件常见的工程措施,但开孔的同时加大了引航道内的流速,对船舶在引航道内航行和停泊构成影响。采用概化物理模型试验,研究了导航堤不同开孔位置、开孔率和不同孔口淹没水深条件下对口门区和引航道内通航水流条件的影响,结合国内外的有关研究成果,提出了开孔的布置原则,为工程设计提供参考。

Opening of guiding dike is a common engineering measure which can improve the flow condition for navigation at entrance area,at same time,it can increase thc flow velocity and influence ship sailing and mooring in the approach channel.The effect of different location of openings,different rare of holes and different submerged water depth conditions on entrance area and flow condition for navigation of approach channel is investigated by a generalized physical model test.The paper combined research results at home and abroad,put forward the principle of opening arrangement and gave reference for project design.
