摘要
针对连云港投放礁体海域的波流状况、水深等设计了十字型礁体,并根据波流动力学理论计算了此礁体受到的最大作用力。该十字型礁体在波流共同作用下的最大受力为2940 N,作用力矩为5699 N·m。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。
Based on the states of wave and current, depth of water and action of fish at the sea cast reefs in Lian Yungang, a cross-reef was designed in this paper. The maximum force subjected to wave and current was calculated out according to the hydrodynamics of wave and current. The maxi-mum force and torque are 2 940 N, 5 699 N·m respectively. Compared with the static friction force and weight torque of the reef, the requirement of its stability is met, that is, the reef doesn' t slide or roll at the floor of sea.
