| 摘 要： | 在线性海浪方向谱折绕射联合模型基础上，通过引入破碎波高概率分布和单个破碎波的处理方法，提出了在能量控制上与我国港口工程规范基本等效的近岸波浪破碎方向谱模型，使海浪方向谱折绕射联合模型的透用范围拓展到破碎带内。模拟地形上的数值计算实验表明，该模型既能从宏观上较好地控制破碎波在沿程能量变化，又能通过波浪的内在结构反映近岸波浪的变形特征。

| Abstract: | A new form of breaking model for nearshore directional wave spectrum was set up.It is based on the statistical decaying model for random breaking wave and can perform similar macro energy control as required by the technological standards for harbor engineering in China.It enables the combined reflection and diffraction model to be suitable for waves in a surf zone.Numerical tests were also done on the supposed topography,which yields reasonable wave height distribution and reveals the main spectral characters corresponding with the wave transforms in shallow water. |
