摘　　要：船舶航行安全事故的频发将业界对船舶破损剩余强度的研究推向了新的热潮.基于破损后船体剩余极限强度与外部最大载荷的指标,对某集装箱海船在碰撞和搁浅两种破损状况下的剩余强度进行了快速、有效的评估.其中,外部最大载荷依据散货船共同结构规范(CSR-JBP)计算;破损剩余强度创造性地采用非线性有限元方法求解,与假想应力法对比计算结果较好.The high frequency of navigation accidents sets off a new upsurge of research on damaged ship hulls＇ residual strength.This paper took a rapid and effective assessment to the residual strength of a damaged container ship after collision and grounding respectively based on the index of residual strength and ultimate loads.The loads are calculated according to the CSR-JBP while residual strength according to non-linear FEM which shows a good result comparing to analytical method.This method is based on design,having directive significance to engineering design and marine rescue in a great degree.

关 键 词：剩余强度 非线性有限元 碰撞 搁浅
