摘　　要：介绍了利用数值模拟技术来模拟海浪的波面以及水质点的水平速度和加速度的主要方法,同时以P-M谱为靶谱,利用线性过滤法模拟了波面以及固定高度处水质点的水平速度和加速度,并与靶谱进行了比较。The methods of numerical simulation technology for wave surface and the velocity and acceleration of water particle were discussed.Meanwhile linear-filtering method was used to simulate wave surface and the velocity and acceleration of water particle in a fixed height.The results were compared with target spectrums(P-M spectrum).

关 键 词：数值模拟 谐波叠加法 线性过滤法
