摘　　要：研发一型采用“泵进流出”开式循环水养殖系统的养殖平台,通过海水泵将外界环境海水抽进养殖舱内,在养殖舱底部设置开孔将舱内养殖尾水自然排出,养殖舱始终与外界海水保持联通,内外液面持平且需要考虑自由液面对稳性的不利影响。针对在平台的完整稳性和破损稳性计算校核中实际反映开式养殖水舱与外界海水联通且考虑大面积自由液面的特点,结合现行规范的具体要求和浮体稳性原理进行分析,应用NAPA软件进行不同模式组合的计算验证,结果表明,完整稳性和确定性破损稳性中推荐采用考虑养殖舱浮力的计算模型,概率性破损稳性中推荐采用扣除养殖舱浮力的计算模型。The large-scale circulating aquaculture platform was developed adopting the‘pump in and flow out’open circulating aquaculture system,in which the external seawater is pumped into the aquaculture cabin with the seawater pump,and the tail water is naturally discharged through the opening at the bottom;the aquaculture cabin is always connected to the external seawater,so the internal and external liquid levels are the same,and the adverse effect of the free liquid surface on the stability needs to be considered.Considering the characteristics of that the open aquaculture tank is connected to the sea water and a large area of free liquid surface should be considered,in view of the specific requirements of the current rules and the floating body stability principle,the NAPA software was used to calculate and check the intact and damage stability of the platform under the combination of different modes.The results showed that the model considering the buoyancy of the aquaculture tank is recommended for the intact stability and the deterministic damage stability,and the model deducting the buoyancy of the aquaculture tank is recommended for the probabilistic damage stability.
