文章基于高阶近似抛物缓坡方程 ,利用线性叠加原理建立了自然地形条件下综合考虑水波折射、绕射的随机波模型。通过对 Vincent和 Briggs的不规则波实验资料的数值模拟 ,对本模型进行了验证 ,计算结果和实验结果符合得比较好。并且通过数值计算得出了一些重要结论 ,对工程计算有重要意义。

A random wave model combining wave refraction and diffraction has been developed,which is based on the higher order approximation parabolic mild slope equation and uses the linear superposition theory.By comparison with the irregular experiment of Vincent and Briggs,the results of calculation agreed well with that of experiment.Some conclusions derived from the numerical calculations will be important for practical engineering calculations.
