| 波浪能作为一种可再生海洋清洁能源，其开发利用对建设绿色港口具有重要意义。将振荡水柱式（oscillating water column，简称OWC）发电装置与码头结构相结合，提出了一种兼做防波堤的集成OWC波浪发电装置的圆沉箱与吸力桶整体预制式离岸深水码头结构，这种新结构具有整体刚度大、耐久性好、施工作业时间短和可适用于软土地基的优点。使用水动力软件FLOW-3D建立新型结构的三维水动力模型，系统研究了不同前墙入水深度、透平开孔率及入射波高时新型结构在波浪作用下的水动力特性，并计算了其波能转化效率。结果表明，新型结构的波能转化效率随入射波高增大而增大，随透平开孔率及前墙入水深度的增加呈现出先增后减的趋势，在前墙入水深度取7.5 m，透平开孔率取6%时，波能转化效率最大可达49.04%。同时，本研究提出的新型离岸深水码头结构上所受的波浪力相比未开孔结构大幅降低，实现提高码头安全度和利用绿色能源的双收益。建议在实际工程设计中适当提高气室开孔的高程或设置防护措施，以保证波能转换装置免受极端波浪的影响。 |

| As a renewable marine clean energy resource, wave energy development plays an important role in advancing green port construction. This study proposes an integrated offshore deep-water wharf structure that combines an OWC (oscillating water column) power-generation device with breakwater functionality, featuring a precast circular caisson and suction bucket configuration. The innovative structure offers advantages such as greater overall stiffness, improved durability, shorter construction duration, and suitability for soft soil foundations. Using the FLOW-3D hydrodynamic software, a 3D hydrodynamic model of the new structure is developed to systematically examine its behavior under different parameters, including front wall immersion depth, turbine opening ratio, and incident wave height. The results indicate that the wave energy conversion efficiency increases with incident wave height, while both the opening ratio and immersion depth show a pattern of initial growth followed by decline. A maximum conversion efficiency of 49.04% is attained at a front wall immersion depth of 7.5 m and a turbine opening ratio of 6%. Furthermore, the wave forces acting on the proposed offshore deep-water wharf structure are substantially reduced compared with the non-perforated configuration, providing dual benefits of enhanced structural safety and renewable energy utilization. It is recommended that practical design considerations raise the elevation of the air chamber openings or adopt protective measures to ensure that the wave energy conversion device is protected from the impact of extreme waves. |
