The characteristics of random wave propagating to the region where obstacles exist are computed by refraction-diffraction combined mode of seawave spectra, and the processing methods of boundary value in the back wind region of obstacle are presented. The theoretical results agree well with the observations, which show that the mode and the methods are effective to figure out wave characteristics in the obscure regions behind obstacles.

本文应用海浪谱绕射模型计算了不规则波传播至有障碍物(如半岛)的水域的海浪要素。文中给出了障碍物背风面边值的处理方法,比较了理论值和实测值的结果,符合良好。说明缓坡上海浪谱折绕射联合模型和文中给出的边值处理方法,对障碍物后遮拦区波要素计算是有效的。

Random wave surface was simulated using given target spectra and the experiments of random wave propagation on mild-slope models were carried out. The numerical calculations of refraction-diffraction of sea-wave spectra were performed with different target spectra and topogra-phies. The comparison between the measured results and spectral structure and those of numerical calculations showed that the refraction-diffraction combined mode of sea wave spectra on mild slope bottom is effective,dovetailed to the experiments...

Random wave surface was simulated using given target spectra and the experiments of random wave propagation on mild-slope models were carried out. The numerical calculations of refraction-diffraction of sea-wave spectra were performed with different target spectra and topogra-phies. The comparison between the measured results and spectral structure and those of numerical calculations showed that the refraction-diffraction combined mode of sea wave spectra on mild slope bottom is effective,dovetailed to the experiments of random wave propagation on mild-slope models. It is a very economical and convenient method.

文中以给定靶谱模拟随机波面,并对在缓坡中传播着的随机波进行了模型实验。同时,用不同的靶谱和底形进行了海浪谱绕射的数值计算,并比较了实测值和计算值及其谱形结构。结果表明缓坡中海浪谱折绕射联合模型用来数值计算缓坡中传播的随机波是有效的,它等价于随机波的绕射模型实验,是一种既经济又方便的方法。

Composed of directional distribution of wave energy and control equations of wave component refraction - diffraction, a combined refraction- diffraction model of directional wave spectrum was made. Numerical calculation by the mode with different directional distribution was carried out on supposed topography. Compared with solutions of simple wave and frequency spectrum refraction - diffraction, calculations with scattered directional distribution of wave energy could not only smooth the energy convergence...

Composed of directional distribution of wave energy and control equations of wave component refraction - diffraction, a combined refraction- diffraction model of directional wave spectrum was made. Numerical calculation by the mode with different directional distribution was carried out on supposed topography. Compared with solutions of simple wave and frequency spectrum refraction - diffraction, calculations with scattered directional distribution of wave energy could not only smooth the energy convergence and divergence on topography but also change positions where they took place.

本文考虑海浪能量在方向上的分布,结合组成波绕射控制方程组,建立了海浪方向谱的折绕射联合模型,并在简单地形上实施数值计算.比较简单波及能量谱绕射的计算结果,表明:考虑海浪能量的方向分布,能减弱波动能量辐聚、辐散的程度,改变辐聚、辐散的位置.方向分布形式不同,这种影响表现出的程度也不一样.
