| 摘 要： | 基于船舶不沉性理论，运用符拉索夫抗沉性计算法确定船舶破损后浮态参数之后，作出波浪上船舶破损浮力曲线，继而计算了波浪弯矩和波浪剪力；并用非对称梁弯曲理论建立了破损模型，将外载荷与破口联系在一起研究了破损船舶极限弯矩，通过实例计算得出了预想结果。

| Abstract: | Based on theory of floodability, the paper applies Vlasov's calculation method to determine the floating parameters of damaged hull, discusses the buoyancy curve of damaged hull on wave, and calculates wave bending moment and wave shearing force. The asymmetrical beam bending theory is applied to set up damaged model. The paper also discusses the ultimate bending moment of damaged hull by integrating external loads with damaged points. Expected results of examples are obtained. |
