摘　　要：基于MIKE 21-SW风浪数值模型,将1980年以来在泰国湾过境的最强台风“盖伊”作为典型台风,计算了该台风过境期间泰国马达普港海域的台风浪。通过对比美国海岸防护手册推荐的最大台风浪计算经验公式,得到该手册计算结果与本文模型模拟的泰国湾最大台风浪结果基本一致。模拟结果表明防波堤外侧有效波高为4.4 m,谱峰波周期为11.5 s,平均波向为162°;港内泊位在多级防波堤掩护下,有效波高衰减为2.2 m。本文模拟技术可供“一带一路”其他沿线工程海域在缺乏气象水文资料前提下的台风极值浪研究参考。MIKE21-SW model is used to simulate the variation of stormy waves in MTP port caused by typhoon GAY while it is passing over Thailand Gulf.By comparing with the empirical formula for the maximum typhoon waves recommended in U.S.Shore Protection Manual(SPM),the calculation results based on SPM are basically consistent with the simulated results of the maximum typhoon waves in the Gulf of Thailand.The simulation results show 4.4m effective wave height in front of the breakwater;11.5 s peak spectrum period,and 162°mean wave direction.Being shielded by multi-level breakwater,the effective wave height in the harbor basin is reduced to be 2.2 m.The above simulation technology will serve as a reference for the study of extreme typhoon waves in the sea areas covered in The Belt and Road Initiatives subject to no meteorological and hydrological data provided.
