三亚湾海洋牧场人工鱼礁结构设计及稳定性分析

作者基于海南三亚湾海洋牧场海域的海况条件、渔业资源状况,根据波流动力学理论设计一种箱形鱼礁礁体以聚集鱼类,并对该礁体进行了稳定性计算。结果表明,该礁体在实际投放水深为–25 m、波高为8.45 m、流速为0.8 m/s时,礁体最大受力为27 422 N,滑动安全系数为1.55,滚动安全系数为2.49,满足礁体稳定条件,在研究海域不会发生漂移及倾覆,能为今后海南省人工鱼礁建设提供重要的理论依据。

Structure design and stability analysis of the artificial reef in marine ranching of Sanya Bay

For the marine ranching of Hainan Sanya Bay, a box-style reef for gathering fish has been designed, based on the states of the sea area and fishery resources. In this paper, we calculate the stability of the reef based on the hydrodynamics of the waves and currents. We determined the maximum force to be 27 422 N and the anti-slide and anti-rolling coefficients to be 1.55 and 2.49, respectively. When the water depth reaches 25 m, the wave height reaches 8.45 m and the velocity of flow reaches 0.8 m/s. These calculation results indicate the effective stability of the reef, which will not slide or roll in this sea area.
