海浪仿真是海洋工程的热点话题。本文总结了一种可以适应于各种随机波浪谱来仿真海浪环境的方法，利用C语言将该方法转换为过程简单、编写方便的计算机程序得到大量仿真波浪数据，并作为造波机输入数据，通过实测数据检验仿真结果。试验证明，采用文中提出的数值方法，采集模拟波高数据利用相关函数法进行频谱估计，得到的模拟谱和靶谱误差较小。该数值仿真方法在海浪仿真上具有实际应用价值。

Wave simulation is a hot topic of Ocean Engineering. This article summarizes a method that can adapt to a wide range of random wave spectrums to emulate the waves environmentally. The method is converted to computer programs which are simple and convenient by language C and compute a large number of data used as data source to wave maker. The simulation result is verified by the experiment data. The test shows that the error between the analog spectrum and the target spectrum is lowest by using the numerical method presented in this paper. The acquisition of analog wave height data are used to estimate the spectrum by correlation function method. The numerical simulation method has a practical application value in the wave simulation.
