摘　　要：为满足电缆和管道等的布置需要,船体梁的腹板开孔会超出规范要求。当腹板开孔超出一定尺寸,规范仅要求进行补强,但并未给出具体的加强参数。针对该问题,采用有限元方法,分析围缘扁钢和复板两种加强方式对腹板开孔梁强度特性的影响,并对加强方式的参数选取进行讨论。In order to satisfy the layout demand of cables and pipes,there are always web openings whose parameter exceeds the regulations of rules.When the web openings exceed a certain size,the rules only requires reinforcement,but does not give specific reinforcement parameters.FEA was used to assess and compare the strength of beams with web openings strengthened byflat steel and doubling plate respectively.The parameter determination of the strengthening method was also discussed.

关 键 词：腹板开孔 强度特性 开孔加强
