摘　　要：为研究深水养殖平台的水动力特性及其锚泊系统的安全性,以“振渔二号”深水养殖平台为例,开展物模试验和数值仿真计算。测试该平台在极限风速和流速下的外载荷作用力,并对其进行规则波频率运动响应试验和数值模拟,同时对其锚泊系统进行风、浪、流联合作用下的运动和系泊受力试验,获得该平台的水动力及其锚泊系统的受力特征值。物模试验和数值计算结果表明:忽略网衣的影响,纯波浪作用对平台运动的影响较小;在横风、横浪、横流作用下,锚泊系统最大受力对应的安全系数满足船级社相关指南的要求,有一定的安全裕度。研究成果可供深水养殖平台及其锚泊系统的优化设计和作业安全评估参考。The hydrodynamic characteristics and mooring safety of the deep-water aquaculture platform ZHENYU No.2 is studied with the fishing net modeled based on Froude similarity criterion.The external force on the platform under the extreme wind speed and flow velocity is tested,and the frequency response of the platform to regular waves is studied through experiments and numerical simulation.The forces on the mooring system when moving and moored under the combined action of wind,wave and flow are tested to get the characteristic values of platform hydrodynamics and the forces acting on the mooring system.The results of numerical simulation and test show that,when ignoring the influence of the fishing net,wave itself has little effect on the motion of the platform.The safety factor of mooring system under cross-wind,cross-wave and cross-current action meets the requirements of relevant guidelines of classification society with a certain safety margin.
