摘　　要：从推导造波板的运动规律出发,讨论了海洋工程水动力学试验中白噪声不规则波及聚焦波这2类非常规波浪在水池中的生成技术;基于实测谱修正与波谱相位聚焦,在海洋工程水池生成了品质较好的白噪声不规则波与聚焦波,并给出了这2种波浪在水池中的测试结果.通过边界元数值计算方法对水池模拟的聚焦波进行了验证.结果表明:采用所述方法可以在试验水池中生成品质较高的白噪声不规则波及聚焦波,从而为提高常规海洋工程水动力试验的精度,缩短试验时间及后续开展海洋工程平台在恶劣海况中生存能力的研究提供了技术依据.By deriving the movement rules of wave-maker,the technology of generating two types of unconventional wave white noise irregular wave and focused wave which were used in offshore engineering hydrodynamic experiments was discussed.Based on measured spectrum correction and phase focusing of component waves,white noise irregular wave and focused wave were produced,and the experimental results were presented.Meanwhile,focused wave simulated in basin was also verified by boundary element method.The basin test results demonstrate that good quality white noise irregular wave and focused wave can be generated according to the methods given by this paper.Moreover,the simulation technology of these two types of wave can be used as the basis to improve the credibility of model test,shorten the test time consumption,and well carry out the research of the offshore platform′s survivability under serve sea state.
