摘要
根据人工鱼礁礁体设计的基本理论和原则,考虑实地投放条件和投放要求,对船形混凝土人工鱼礁进行结构设计和沉降计算。计算得到礁体的横稳心高度(?)约为0.56 m,满足一般船舶在海面的稳性设计要求;船形礁于海面4 kn拖速下所受拖曳阻力R_F值为318.04 N;礁体在水深30 m海域投放,最终速度为2.49 m/s,沉降时间13.41 s;通过计算礁体着底时的底冲力为150.00 kN,换算得出鱼礁结构强度均布荷重q(213.78 kN/m),为礁体建造时的强度要求提供依据。
Based on the theory and principia for artificial reef design, even the condition and requirement for deploying on the spot, this paper makes some calculation in the reef design and subsidence. The transverse stability GM^- of reef is 0. 56 m that can conform with the need of boat designment; towrope resistance RF on sea surface is 318. 04 N when reef drawn on sea at the speed of 4 kn, ; reef is set at the sea with 30 m depth, the final speed is 2. 49 m/s, and the setting time is 13.41 s; from the calculation of bottom impulse（150.00 kN） when reef landing the seabed, the equispaced weight（213. 78 kN/m） of reef structur-al strength can be converted, which can provide the reference of strength requirement for reef building.
