摘　　要：针对避风港港池内的波流影响船舶安全等问题,用计算流体动力学模型,分别模拟了避风港口门相对于码头的5种位置布局和三种口门宽度(20、40、60 m)工况下,港池外波高分别为1、2、4 m的规则波传入港池后波浪消减率及可能形成的环流危险区域,模拟结果表明:港池口门偏离码头角度最大时,港池内波浪消减率最大,是较适宜的口门位置;在此条件下,口门越窄,环流区越多,不利于船舶安全,限制了通航能力。研究发现口门宽度为40 m时,既能保证船舶进港率,又能保障港池安全,在此基础上提出了合理的进出港航线。In order to solve the problems with ship safety caused by waves and current in the harbor basin, the computational fluid dynamics (CFD) model was used to simulate wave attenuation and potential dangerous zones with the scenarios of the layouts of the five different posi tions of the entrance of width of 20 m, 40 m and 60 m respectively and approach regular waves of 1m, 2 m and 4 m in height separately. The results of the modeling show that when the entrance is so located that a largest angel between the line linking the dock and the entrance and the alignment line of the dock is formed, the wave attenuation rate will become the largest, which means a suitable location of the entrance. For the suitable entrance position determined, it is found that the narrower the entrance is, more circulation areas are found formed in the harbor, which is not favorable for ships safety and also limits the navigation capacity to a lower level. It is found that entrance width of 40 m is able to ensure both the ship inbound rate and the safety inside the harbor. With these parameters determined, a reasonable inbound and outbound route is proposed.
