摘　　要：船舶在航行过程中有可能发生船体破损以至船体进水的情况。因此,应该考虑船舶的抗沉性和应对措施,使船舶在一定程度损伤后仍具有足够的航行能力。在对船舶对称破舱的情况进行分析的基础上,采用槽型水舱理论建立了船舶破舱后横摇的数学模型,并对不同破舱水位和流动阻尼情况下的船舶横摇特性作了仿真和分析。最后根据船舶破舱数学模型,讨论并给出了船舶破舱情况下系统的绝对稳定条件。The hull may be broken and flooded during voyage. So the insubmersibility of ship and related disposal should be considered to make the broken ship remain enough navigation capability. The cases of the symmetrical broken cabins of a ship were analyzed. Based on the analysis, a rolling model of ship with broken cabins was proposed according to the theory of slot tank. Several cases with different water level and flow damp in the broken cabins were simulated and the characteristics of ship rolling in these cases were analyzed. Finally, according to the proposed model, the absolute stabilization condition of ship rolling with broken cabins was discussed.
