| 摘 要： | 为了深入了解围填海工程对波浪场特别是风浪场的影响,针对10 a 围填海工程对渤海湾地形岸线的改变,将 SWAN(Simulating Waves Nearshore)海浪数值模式应用到渤海湾,讨论了人类大工程对渤海湾风浪场的影响.采用欧洲气象中心每天4次的风场资料作为驱动,模拟渤海湾2000年和2010年的风浪场,着重分析岸线变化显著的3个港口工程(曹妃甸、天津港和黄骅港)附近海域的波浪要素变化.研究结果表明,工程建筑物存在后,有效波高呈减小趋势,港池和潮汐通道内的有效波高减小幅度较大.港口地理位置和海底地形也与岸线变化共同影响着港口附近海域的波浪场分布.围填海工程对波浪有效波高及周期影响的程度不大,有效波高减小值在0.2 m 以下,周期几乎不变. |

| Abstract: | According to the variation of the Bohai Bay coast line from 2000 to 2010, we established the SWAN(Simulating Waves Nearshore) wave model forced by the ERA wind fields to simulate the wave fields of the Bohai Bay in the years of 2000 and 2010 to investigate how coastal reclamation affects wave fields, especially the influence of the wind waves. The variations of the wave fields near three harbors (the Caofeidian, Tianjin Port and the Huanghua Port), where the coastlines had been changed significantly, were analyzed. The results revealed that the significant wave heights decreased after the coastal reclamation, and the magnitude of decrease of the significant wave heights in the harbor basin and the tidal channels was bigger than that in the other area. Moreover, the locations of the three ports and the topography around them had the combined effects on the distributions of the wind waves near the three portal areas. The coastal reclamation had little influence of the significant wave heights, where the reduction was under 0.2 m, and cycleswell as time which had no changes compared with our experimental data. |
