摘    要:针对台州大陈海域的波流状况、水深等设计了钢制四方台型礁体。礁体的基本尺寸为底座3.5m×3.5m×0.3m,顶面2.5m×2.5m,高3.5m,重7.19。t根据波流动力学理论对此礁体在实际投放海域所受到的最大作用力、抗漂移系数以及抗倾覆系数等进行了计算。结果表明,该钢制四方台型礁体在波流共同作用下的最大受力为32255N,作用力矩为48642 N.m,抗漂移系数和抗倾覆系数分别为1.44,2.23。与礁体受到的静摩擦力、重力矩相比,满足礁体稳定条件,即礁体在海底不会发生滑移或翻滚。

关 键 词:人工鱼礁  四方台型钢制礁体  稳定性

Abstract:Based on the states of wave and current,depth of water and behavior of fish at the sea area of reefs deployed in Dacheng,a steel prism reef was designed in this paper.The basic size of foundation and top side are 3.5m×3.5m×0.3m and 2.5m×2.5m respectively.The height is 3.5m and the weight is 7.19t.The maximum force,coefficient of anti-rolling and coefficient of anti-slide subjected to wave and current were calculated according to the hydrodynamics of wave and current.The maximum force and torque are 32255N and 48642 N·m respectively.The coefficient of anti-rolling and anti-slide are 1.44 and 2.23 respectively.Compared with the static friction force and weight torque of the reef,its stability met the requirements,that is,the reef doesn't slide or roll on the sea floor.
Keywords:Artificial reef  steel prism reef  stability
