摘　　要：针对某滚装船建造时出现严重中垂变形的现象,从船体强度、船体刚度、焊接变形、建造工艺及焊接工艺等方面。分析其产生的原因,并研究整改方案,通过整改成功地将船舶中垂变形值恢复到正常安全范围内。该案例可为类似船舶的类似问题提供技术借鉴,也为薄板船的建造积累了经验。In view of the serious sagging deformation during the construction of a Ro-Ro ship, the causes from the aspects of hull strength, hull stiffness, welding deformation, construction technology and welding procedures are analyzed, the rectification program is studied, and the sagging deformation value of the ship is successfully restored to the normal and safe range through the rectification. The technical reference can be provided for similar problems of similar ships, and the experience is also accumulated for the construction of thin plate ships.
