单方向不规则波模拟与统计中的几个问题

Problems on Simulation and Statistics of Unidirectional Irregular Wave

单方向不规则波,由于其过程的随机性,在模拟中经常遇到波谱类型,模拟时间长度及初始相位的选定等问题,文中结合模拟统计与实践经验对其中几个问题进行了探讨,提出了在模拟研究中应对特征周期进行统计、用伪随机数优化缩短模拟时间等结论。

Application of unidirectional irregular wave in study of wave due to harbor engineering is more generalized. As its randomness, sometimes the problems, such as type of wave spectrum, length of simulating time and selection of initial phase, etc., have to be tackled. Therefore, some of them are discussed on the basis of simulation and statistics. And it' s concluded that in simulation studies, the characteristic periods should be counted and the simulationg time should be optimized and shortened with pseudo-random numbers.
