摘  要:
针对我国南海北部湾东部投放藻礁海域的海况条件,设计圆台型人工藻礁,以实现该海域马尾藻的人工增殖与移植。基于波流动力学理论,计算圆台型人工藻礁礁体不同海流速度下的作用力、抗滑移系数及抗翻滚系数,探讨礁体的稳定性。结果表明:在波、流共同作用下,礁体最大受力为171.8 N,最大作用力矩为49.64 N·m,抗漂移系数S1范围为2.88~25.09,抗倾覆系数R1范围为2.06~315.00,满足礁体稳定条件,礁体在该海域正常情况下不会发生漂移或倾覆现象。

摘  要:
Based on the conditions of the sea area of reefs deployed in the east of Beibu Bay in the South China Sea, a frustum-shaped artificial reef is designed in order to achieve Sargassums' artificial reproduction and transplantation. The maximum force, coefficient of anti-slide and anti-rolling of reef are calculated under different flow velocity according to the hydrodynamics of wave and current. The maximum force and torque are 171.8N and 49.64 N·m, the rang of coefficient of anti-slide and anti-rolling are 2.88 – 25.09 and 2.06 – 315.00, respectively, the minimum are 2.88 and 2.06 respectively. The result of the calculation achieves the object of the stability of the reef, ensuring the reef not to slide or roll in this sea area.
