摘 要: 船舯断裂的主要原因之一是船体构件因长期受到腐蚀、疲劳等作用而造成船舯剖面模数降低 ,进而削弱了总纵强度 .文中通过对一老龄散货船船舯断裂问题的研究 ,提出了一种实测 -计算剖面模数法 .该方法简单易行 ,且与环带测厚法相比 。 The rupture in the middle of bulk cargo is due to the corrosion and fatigue of components in long term usage, which leads the sec tion modulus to reduce and the general longitudinal strength to weaken. In this paper, through the research of the rupture of an old bulk cargo in middle, a new method named 'test_calculated s ection modulus method' was proposed. The method is easy to realize. Comparing w ith the 'zone thickness_survey method', the method proposed here proves reason able.
