摘　　要：针对航行船舶在不同装载工况下,船体梁会产生中拱、中垂变形的问题,以某船为例,通过经验公式计算和基于船舶静力学推导出的修正法对排水量进行修正对比,以坦谷波法对船舶总纵强度进行修正,结果表明,船体梁拱垂变形会导致船舶难以达到最大设计的排水量,“削低”了船体梁在静水、波浪中的弯矩的峰值。In view of the problem that the ship hull girder will inevitably produce hogging and sagging deformation under different loading conditions,taking a large ship as an example,the displacement was corrected and compared by the empirical formula and a new correction method based on ship hydrostatics,and the longitudinal strength of the hull girder was corrected by trochoidal wave method.The results showed that the sagging deformation of the hull girder will make it difficult for the ship to reach the maximum design displacement and reduce the peak value of the bending moment of the hull girder in still water and waves.
