摘　　要：考虑到目前国内对纵向箱型结构的设计及抗损能力研究不够充分,在常规方案的基础上构建包含纵舱壁结构或纵向箱型梁结构的多方案结构形式,计算不同爆点下各结构形式的毁伤效应及剩余承载能力,结果表明,纵向箱型结构能有效提高舰船的剩余承载能力。At present,domestic research on the design and damage resistance of longitudinal box structures is insufficient.On the basis of the conventional scheme,a multi-scheme structure type including longitudinal bulkhead structure or longitudinal box-girder structure was constructed.The damage effect and residual strength of each structural type at different explosion locations were calculated.The numerical results showed that the longitudinal box structure can effectively improve the residual bearing capacity of the ship.
