| 摘 要： | 通过建立波浪潮流数学模型,对"奋威"轮沉船坐浅期间海域水动力条件进行模拟计算。结果表明:(1)沉船仅对局部海域的流态有影响,总体影响不大,沉船附近涨落急时流速为1 m/s左右;(2)沉船坐浅期间,沉船附近最大波高可以达到2.63 m左右,大风情况下的巨浪可能对沉船的稳定性造成影响。模拟结果为沉船沉降计算提供水动力条件。

| Abstract: | Mathematical models with wave and tidal current in the W.D.Fairway Sunk Dredger sea area are set up,and the hydrodynamic conditions are numerically simulated.The study results show that：（1） The ship of W.D.Fairway only influenced the local flow field near the ship and the total influence is little.The maximum velocity of the flood and ebb flow is about 1 m/s around the ship.（2）During the ship sitting shallow,the maximum wave height reaches approximately 2.63m during the large wind process,It is concluded that the large waves caused by the large wind processes may affect the stability of the ship.The results provide the hydrodynamic conditions to the settlement calculation model |
