摘　　要：中马友谊桥海域波浪以涌浪为主,但其海浪特性及传播机理尚不明确,给桥梁防护与运营带来极大困扰。采用波浪模型Mike21 SW,以ERA5资料作为驱动风场,对中马友谊桥海域的波浪进行数值模拟获得数据结果,并对该海域的海浪特性进行溯源分析。结果表明:受季风洋流驱动的影响,中马友谊桥海域的波高为0.45~0.85 m,7月和8月的波况较差;波周期多介于6.0~10.0 s,其频率占全年的53.15%,为显著的中长周期波。马尔代夫海域的涌浪主要来源于印度洋涌浪,且受其向北传播影响,因此该海域波向常年呈E—S向(东—南向波浪),桥梁位置受岛屿遮蔽,常年保持SE向。Waves in the China-Malaysia Friendship Bridge sea area are mainly surges,but their characteristics and propagation mechanism are still unclear,which brings big trouble to the protection and operation of the bridge.In this study,the wave model Mike21 SW driven by the ERA5 data is used to simulate the waves in the China-Malaysia Friendship Bridge sea area,and the characteristics of the waves in the study area are obtained retrospectively.The results show that:affected by monsoon current,the wave height in the study area ranges from 0.45 m to 0.85 m,and the wave condition is bad in July and August;the wave period mostly ranges from 6.0 s to 10.0 s,and the frequency accounts for 53.15%of the whole year,showing a significant feature of medium-long period waves.Maldives sea swell mainly originates from the Indian Ocean swell,and are influenced by the northward propagation of the Indian Ocean swell,the wave direction of Maldives sea is E-S all year round,and the location of the bridge is sheltered by the island,which keeps SE direction all year round.
