摘　　要：我国现行《舰船通用规范》适用于设计水线长不超过160m的水面舰船,当设计水线长在160～200m时,规范规定参照执行。随着舰船的尺度逐渐加大,波浪载荷的计算问题更加复杂。比较了4种规范的波浪载荷计算公式,并应用线性切片理论,采用短期和长期预报的方法,计算大尺度舰船的垂向波浪诱导弯矩值。因此,对于一定范围内的大尺度水面舰船,采用"通用规范"所得波浪载荷值计算船体强度还有一定安全性,并可运用多种计算方法合理选取波浪弯矩值。The current rules of General Specifications for Ships are applicable to the ships of length less than 160 m only. For the ships＂ length of 160-200 m, it should be carried out as referential standards. Wave load calculations of those ships with larger dimensions become more complicated to deal with. This paper compares four calculation formulae for wave load given by the different rules. Prediction methods of both short-term and long-term are used to calculate the values of vertical wave induced bending moment for large scale ships according to the linear strip theory. It demonstrates that it is still safe to utilize the results of wave load calculations for ships within a scope of larger dimensions based on the general rules. Rational bending moments could be obtained by a combination of calculation methods.
