摘　　要：利用波能聚焦的方法在水池中模拟产生多向聚焦波浪,研究了多向极限大波作用在垂直圆柱上引起的波浪力的特点。实验中研究了不同的波浪参数,如聚焦波幅、谱峰频率、频率宽度和方向分布等多向聚焦波浪对圆柱作用的影响,并将实验结果与二维实验结果进行了比较。结果表明聚焦波浪参数对圆柱作用力具有明显的影响,并且实验结果与二维规则波结果相当,但比二维聚焦波浪实验结果要小。The wave focused method has been used to generate multi-directional focused wave in a wave basin and the force of multi-directional extreme wave on the cylinder has been investigated considering different wave parameters. The effects of wave parameters on interaction between wave and structure have been analyzed and the experimental data have been compared with 2D experimental data. The results show that the wave parameters have significant effects on extreme wave impact on the cylinder. The multi-directional experimental results give a well agreement with the results in regular wave case, but smaller than two-dimensional results.
