摘　　要：为研究不同形式内河码头对其近岸水流的影响,应用mike21软件对不同形式码头修建前、后其近岸局部流场、过流区域过流量和Fr数变化情况进行了数值模拟分析。结果表明:不同形式码头对近岸局部流场影响差异很大,码头修建需合理选择码头位置、形式及规模,防止码头近岸产生不良流态水流;河道岸壁边界的改变对近岸区域水流有较大影响,且二者的相互关系较为复杂,应看成一个系统。In order to study the influence of different patterns of inside river wharfs on the near-riverbank water flow, MIKE21 soft- ware is applied for the numerical simulation of the local near-riverbank flow field, and discharge （Q） and Froude number （Fr） in this zone are analyzed. The simulation results show that the patterns of wharfs have a significant effect on the local near-riverbank flow field, and the construction of wharfs needs to choose properly the location pattern and scale of wharfs to prevent adverse flow pattern near the wharfs. And the change of riverbank boundary has a greater effect on the near-riverbank water flow, both of them should be seen as a system because of a more complicated relationship between them.
