摘　　要：考虑船体发生碰撞和搁浅破损后,其剩余有效剖面是非对称的、船体还可能发生不同程度倾斜的实际情况,采用逐步破坏分析方法计算破损船体在不同倾斜情况下的剩余极限强度,避免了已有研究中按直接法计算时,对破损船体仍按正浮时的应力分布假定的问题.计算了多种船型在各种不同的破损情况下破损船体的剩余极限强度,给出了一条实船的计算实例及结果分析.The aim of this study is to analyze and assess the residual ultimate strength of damaged ships, considering the asymmetry of damaged hull girder cross section and also the different inclination conditions after grounding and collision. It is the first time to apply the progressive method for this kind of study. The advantages are that it needn＇t use assumed stress distribution as such in applying the direct method. Several ship types have been investigated for accidental situations and the results of a bulk carrier are presented as an example. The method developed in this paper should be useful for ship preliminary structural design.
