摘　　要：本文针对洋山深水港建设引起的洋山海域波浪特征的变化进行分析研究,通过对长序列洋山波浪观测资料分析,确定SE、NW、S、NE、E 5个典型浪向为代表浪向,采用基于波能守恒的第三代波浪模型,计算建港过程间隔10a的2个典型建设时期,即洋山建港初期(2002年)和洋山建港后期(2012年)的极端高水位下50a一遇波浪场。研究表明,10年洋山深水港的建设使港区内的波浪场分布发生了显著的改变,工程建设后期港区NE、E、NW向波高均有不同程度减小,目前港区前沿受SE向波浪影响明显,50a一遇波高可达2.5m以上,波向基本与工程前沿走势保持一致,4期工程前沿NE向波周期增加6.6%,对船舶作业及靠离港的安全有一定影响,需引起关注。Based on the study of the long-range history ocean wave observation data of the Yangshan sea area,represented by five typical wave directions including SE,NW,S,NE and E;selected the interval of two typical construction periods of ten years,the Yangshan Port early building period (2002)and Yangshan phase iv construction period (2012),and used a third-generation wave model based on wave energy conservation,we calculated the wave field at the extreme high water level with a return period of 50years in order to deeply study the change of sea wave characteristics in ten years of construction of Yangshan deep water port.The study showed that the construction of Yangshan deep water harbor in ten years has changed the wave field distribution significantly.The strongest wave direction changed from NE to SE.The changed included also the intensity,height and period of wave.A larger special area,in particular,needs to be attended.
