摘要
对目前常用于港口海岸工程的波浪数学模型进行了回顾,主要介绍了以下四类数学模型,即(1)波向线折射模型,主要介绍波向线法和针对复杂地形的波谱折射的逆波向线法;(2)缓坡方程,大致有三种形式的缓坡方程,即椭圆型,双曲型,抛物线型;(3)Boussinesq浅水短波方程;(4)角谱模型。并对不同数学模型的特点、适用范围和发展趋势进行了对比、分析。
The paper reviews some advanced mathematical models that can be used for description of wave climate in port and coastal engineering . It shows four types of mathematical mod els, which are (1) Wave ray refraction models(This paper introduces the ray method and the back ?tracking ray refraction model of wave spectra); (2) Mild - slope equation wave model (This paper introduces three kinds of equation i. e. the elliptic mild- slope equation, the paraholic mild slope equation and hyperbolic mild -slope equation) ; (3) Boussinesq wave models; (4) Angular spectrum model . This paper also describes the characteristics . application and development of these mathematical models.
