铁山湾海域风浪数值模拟研究

随着北部湾的快速发展，铁山湾海域将规划建设数百个泊位．基于SWAN建立了该海域风浪数学模型，选取铁山湾海域影响较大的5个风向，研究不同风要素组合作用下的波浪特征，计算得到了建港方案实施前、后的波浪场分布．研究结果表明：S-SSW风向对该海域的风浪影响最大，SE-SSE和SW-WSW风向次之，E-ESE和W-WNW风向的影响相对较小．建港方案实施后，工程区的波浪强度整体小于工程前的；人工岛起到了很好的掩护作用．

Numerical simulation for wind waves in Tieshan Bay

With the rapid development of the Beibu Bay, hundreds of berths will be con- structed in Tieshan Bay. The Tieshan Bay＇ s wind wave＇ model has been established based on SWAN model. Combining with the port construction project, the model was applied to study on Tieshan Bay＇s wave characteristics under different combination con- ditions of wind direction, wind speed and recurrence period. Wind wave＇s field distribu- tion results have been obtained by numerical simulation of wind waves of the pre and post port construction in Tieshan Bay. Numerical simulation results show that the wave intensity of project area become weaker after the port construction. The artificial island of the project has played a good role. The S-SSW direction has the biggest influence on the wind wave of the simulation area, the SE-SSE and SW-WSW direction come second, the influences from E-ESE and W-WNW direction are relatively less.
