摘　　要：针对多艘耙吸式挖泥船泥舱中部区域箱形肋板与纵舱壁交接处上端部因裂纹而渗漏的事件,对其成因展开研究,并结合定性分析及强度校核,对耙吸式挖泥船泥舱箱型肋板结构进行优化,使泥舱底部结构获得足够的强度和刚度。By aiming at several Trailing Suction Hopper Dredger （TSHD） crack leakage accidents which happened around the upper end conjunction of longitudinal bulkheads and box ribbed slab in the middle of mud hold ,this paper studies the causes inherent ,and optimizes the structure of the mud hold box ribbed slab by combing the qualitative analysis and strength verification,which ensures the mod hold structure has enough strength and stiffness.

关 键 词：大型耙吸挖泥船 泥舱 箱型肋板 结构优化
