基于《水面舰艇入级规范》《舰船通用规范》，对某船进行垂向波浪载荷计算、总纵屈服和极限强度评估，结果表明：《水面舰艇入级规范》对第二类舰艇中垂状态下的波浪载荷的计算可能对波浪的冲击作用考虑不足；总弯曲应力的计算未考虑纵向构件的失稳和局部载荷引起弯曲应力合成等影响，计算方法偏简单；极限状态下的对波浪的砰击作用可能考虑不够，给出的极限强度储备系数相对偏小。

Taking a real ship as example, the vertical wave loads, as well as the assessment methods of longitudinal yield and ultimate strength of The Classification Rules for Surface Ship and The General Specification for Naval Ships are studied. Comparing between the results of the two specifications, it can be concluded that:for the second type of naval ship, the wave im-pact force in the wave load in sagging condition in the Classification Rules may be not considered enough;the total bending stress calculation is easy, but not considering the buckling of longitudinal member and the composing of bending stress caused by local load;the wave slamming effect under the ultimate state may be not considered enough, and the ultimate strength reservation coef-ficient is relatively small.
