摘　　要：船体货舱段在未安装甲板和顶边水舱的弱结构形式下下水时，保证船体强度是有一定难度的。本文采用有限元方法正确合理地模拟船体下水的实际情况和力学响应，提出了在第3、4压载舱加压载水及在顶部进行适当加强的方案，经济、合理地解决了LPG船下水强度不足的难题。A finite element method is used to simulate the practical launching process and to calculate the mechanical response for a LPG carrier with incomplete hull structure during launching. Some economical and reasonable measures are taken to keep sufficient longitudinal strength of the hull by using the results of this FEM.
