摘　　要：以超强台风"桑美"风场数据为依据,应用考虑波浪折射、底部损耗及波浪破碎等的波谱模型推算近岸海域台风浪场;再应用考虑波浪的浅水变形、绕射、折射、反射、海底摩擦以及波浪之间的非线性相互作用的Boussinesq方程推算港内波浪参数。在此基础上,分析了沙埕港在"桑美"台风正面登陆时港内波浪分布的特征及灾害成因。The paper applies the wind-field data on Super Typhoon Saomai and spectral model to simulate the wave field of typhoon in offshore water.The wave refraction,bottom loss and wave breaking are taken into account in the model.The parameters of waves inside the Shacheng harbour are computed by the use of Boussinesq equation,in which the shallow-water deformation,diffraction,refraction,reflection,seabed friction of waves and nonlinear interaction between waves are taken into account.The distribution characteristics of waves in the Shacheng harbour and the causes of disaster are analyzed,when the Super Typhoon Saomai makes landfall in the harbor directly.
