The rupture in the middle of bulk cargo is due to the corrosion and fatigue of components in long term usage, which leads the section modulus to reduce and the general longitudinal strength to weaken.
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。
Because of the special dimension and working condition of floating dock, the general strength, such as longitudinal strength and transverse strength, was performed strictly to the structure.
对于浮船坞而言，由于其型尺度和作业工况特殊，因此总强度、纵强度、横强度等结构要求比较高。
