| 摘 要： | 针对海工作业平台、海洋养殖网箱等海洋装备的安全防护问题，提出了一种带空气透平的后弯管浮式防波堤，该空气透平既可将作用在防波堤上的波浪能转化成机械能并用于发电，还可显著减小防波堤的锚链力。在介绍了防波堤原理和结构特点的基础上，设计了物理实验模型，并在实验室造波池内进行了模型试验，研究了波浪周期、波高、吃水深度与弯管数量等因素对后弯管浮式防波堤透射系数和锚链力的影响规律。研究结果表明，波浪周期越短，波高越低，防波堤的透射系数越小，锚
链力越小，其消波性能优于传统的浮式防波堤.

| Abstract: | In view of the safety protection of marine equipment such as offshore platforms and marine breeding cages, a back-bending floating breakwater with air turbine is proposed. The main role of air turbine is to convert the wave energy acting on the breakwater into electric power, which can reduce the anchor chain force of the breakwater significantly. Based on the principles and structural features of breakwaters, a physical experiment model was designed and a model test was conducted in the laboratory wave pool. The influence factors such as wave period, wave height, draft depth, and number of bends on the transmission coefficient and anchor chain force of back-bending floating breakwater was studies. The results show that with the decrease of the wave period and wave amplitude, the transmission coefficient of the breakwater is decreased correspondingly, which means this breakwater has clear effect on short-period wave. |
