摘　　要：对预报船舶极限强度的解析公式作局部改进，使其更有效地用于评估或预报现代船舶剩余极限强度。将该方法同MVFOSM相结合，对一艘油船进行了完整船体（新建／老龄）与受损结构（搁浅／碰撞）极限总纵强度分析和可靠性评估及预报；某些结论可作为深入研究剩余强度理论或指导实船结构设计的参考。The analytical formulations for predicting the ultimate strength of ships are partiallymodified so that assessment and prediction of residual ultimate strength for modern shipsmay be more effective. The method is combined with MVFOSM. Ultimate longitudinalstrength analysis and reliability assessment and prediction are made for the intact hull(new construction/aging ) and damaged structure (grounding/collision ) of an existingtanker.
