摘　　要： 根据深圳杨梅坑人工鱼礁区海域的波流、水深等状况,对方型角板中连式礁体和方型对角板隔式礁体进行了不同海流速度下的受力、抗翻滚系数及抗滑移系数的计算。计算结果表明,2种方型礁体所受到的水流作用力随着水流速度的增加而增大,方型对角中连式礁体发生滑移的临界受力为25123N,发生翻滚的临界力矩为91356N·m;方型对角板隔式礁体发生滑移的临界受力为46801N,发生翻滚的临界力矩为170186N·m。研究结果显示,2种礁体的抗滑移、抗翻滚性能均较好,不会因为波流状况的突变而导致滑移、翻滚,投放后能长期维持其功能稳定不变。 Based on the wave conditions,current conditions and water depth of Yang-Meikeng artificial reef area of Shenzhen,the maximum resistance forces,anti-rolling coefficients and anti-slide coefficients of cube-diagonal plate crossing reef and cube-diagonal plate separating reef which have been deployed in the area are computed. The results show that the resistance force of the two reefs increases with sea flow velocity and the increase amplitude of force of cube-diagonal plate separating reef is larger than that of cube-diagonal plate crossing reef. The maximum anti-slide force and the anti-rolling torque of cube-diagonal plate crossing reef are 25 123 N and 91 356 N· m, respectively. maximum anti-slide force and the anti-rolling torque of cube-diagonal plate separating reef are 46 801 N and 170 respectively. The investigation results show that be good enough the anti-rolling and anti-slide performances of the two reefs The 186 will , and the artificial reefs will keep stable and well functioning for a long time even when wave and sea current conditions go worse suddenly.
