对三门湾近一年的实测波浪资料进行了分析，重点研究了台风期间的大浪过程。描述了不同台风期间的波浪特征，包括波高、波周期和波谱。此外，还讨论了台风引起的大浪对系泊船舶的影响。结果表明，研究区主要波向为E，波谱峰值周期大于10 s的占21.48%;台风期间的海浪谱以双峰型为主，涌浪峰值频率在E向0.08Hz左右，不考虑方向的高频风浪相对较弱。观察到了多峰谱和单峰谱。台风作用下的波浪谱峰值周期与系泊船舶横摇运动的固有周期接近。否则，E方向的涌浪与系泊船舶呈约45°的锐角，这可能会增加横摆运动的幅度。
Measured wave data covering 1 year in Sanmen Bay are studied, especially the large wave processes during typhoons. The wave characteristics during different typhoons are described, including wave height, wave period, and wave spectra. In addition, the influence of large waves caused by typhoons on moored vessels is discussed. The results reveal that the dominant wave direction in the study area is E, and 21.48% of the wave spectral peak periods are over 10 s. The wave spectra estimated during typhoons are mainly double-peaked with the swell peak frequency around 0.08 Hz in E direction, and the high-frequency wind seas without regard to direction are relatively weak. The multi-peaked spectra and single-peaked spectra are also observed. The wave spectral peak period during typhoons is close to the natural period of the moored vessels in the roll motion. Otherwise, the swells in E direction are at an acute angle of about 45° to the moored vessels, which may increase the amplitude in yaw motion.
