摘　　要：为了配合救生船潜水系统作业的需要,在船舯部设置了中央月池。该处结构复杂,应力水平较高,月池开口的存在导致了应力集中,使开口部分结构成为船体结构中的危险区域。文章采用理论计算和规范相结合的方法预报了船体外载荷,采用结构有限元分析法与光弹性试验法相结合的方法,研究了月池开口部位的主甲板和船底板处的应力分布和应力集中系数,为优化月池结构提供了依据。In order to cooperate with the working of the rescue ship system, moon-pool is designed in mid-ship. Structures of this area are very complicated, their stresses are high. Moon-pool hole results in stress concentration, which causes the structures near this hole becoming very dangerous. In this paper, external loads of hull are predicted by combining theoretical analysis and rule calculation.FEM and photo-elastic model test are used to study the stress distribution and stress concentration factor of maindeck plating and bottom plating near the moon-pool hole,which presents a foundation for the optimization of moon-pool structure.
