巴西萨尔瓦多某施工海域波浪数值模拟研究

Numerical Simulation Study on Waves Prevailing in a Construction Sea Area in El Salvador,Brazil

本文模拟和分析巴西萨尔瓦多施工海域的波浪动力场,为后续合理安排项目施工顺序提供科学依据。基于率定后的模型,模拟2014年11月~2015年10月巴西萨尔瓦多施工海域的波浪过程。结果表明:5~8月份波况最为恶劣,1 m以上有效波高所占频率超过20%,7s以上有效波周期所占频率介于21.39%~47.85%。由于施工海域被萨尔瓦多海岸环绕,且施工海域的波浪受风场直接驱动,波高较大、中长波周期显著。

By simulating and analyzing the wave dynamic field in a construction sea area in El Salvador,Brazil,a scientific basis is proposed,which helps to appropriately determine the subsequent construction sequence.A rate-determined model is built to simulate the process of wave motion in the construction sea area in El Salvador,Brazil in the period from November 2014 to October 2015.The results show that the worst wave conditions occur in the period of May~August,with the effective wave height above 1 m accounting for the frequency of more than 20%,and the effective wave period above 7 s accounting for the frequency of 21.39%~47.85%.The construction sea area is surrounded by El Salvador coast,and local waves are directly driven by wind field,which lead to large wave height and significant medium and long wave periods.
