浮式防波堤与网箱组合结构的动力特性

Dynamic characteristics of floating breakwater with cage culture function structure

兼具网箱养殖功能的浮式防波堤结构,为深水浮式防波堤和深海网箱养殖提出了一条新的研究思路,不仅解决了海洋工程与海水养殖争地的矛盾,基于防波堤开展养殖的模式更较大降低海水养殖的成本。通过对浮式防波堤兼做网箱的结构进行物理模型试验,得到该结构在不规则波作用下,不同吃水深度、网箱深度以及周期对其水动力特性的影响,结果表明,在短周期波浪作用下,网箱深度为0.1~0.15 m时结构的水动力特性最好。该结构具有良好的工程应用前景。

The floating breakwater structure with cage culture function provides a new research idea for deep-water floating breakwater and deep-sea cage culture.It not only solves the contradiction between marine engineering and mariculture,but also reduces the cost of mariculture based on the breakwater.The physical model test of floating breakwater and cage structure was carried out under the action of irregular waves to learn the effects of different depth of immersion,cage depth and wave period on its hydrodynamic characteristics.The results showed that,under the action of short period waves,the hydrodynamic characteristics of the structure of the cage depth with 0.1~0.15m were the best.The structure has a good prospect of engineering application.
