文摘:本文阐述俄罗斯海军“库尔斯克”号核潜艇沉没事故对潜艇设计、运行和管理等方面的影响，并且从俄罗斯潜艇设计的指导思想、设计原则以及潜艇可靠性、抗沉性等方面对“库尔斯克”号核潜艇事故的教训和启发作了分析和探讨。 - Therefore , the safety of bulk carrier is widely concerned ; the theory of insubmersibility is followed by the introductions of domestic and international regulations , solutions , rules and requirements on the floodability ; introduced are the conditions of hold in flooded condition , and provided are the calculation methodology of the stability and buoyancy when flooding . the concept of cargo permeability is concretely defined , and the calculation methods of the amount of flooding waters are executed ; the application of the influence numbers simplify the calculation of the still water bending moment and shearing force in flooded conditions . a new method to calculate the maximum still water bending moment and shearing force is developed by means of the influence numbers ; the simulation system provides a means of evaluation and forecast on ship ' s danger extent after ship is damaged
在抗沉性公式的推导过程中采用一些假设，并分析了这些假设对结果的影响；然后介绍了船舶强度的概念和计算方法，鉴于现有的剪力弯矩计算方法工作量大、效率不高的缺点，引用影响数计算船舶进水后的剪力和弯矩；最后根据船舶抗沉性理论对散货船破舱进水进行模拟，在模拟中根据船舶破舱的实际危险情况，采用直观的图形输入的办法，判断船舶的危险程度并计算船舶到达危险状态的时间以助于船长做出正确快速的决策。
