极地破冰船冰区结构设计规范对比研究

Comparative study of structural design rules for polar icebreaker ships

通过对各主要船级社关于破冰船结构设计的规范进行比较和分析,研究了不同规范关于冰级定义、船体加强区域划分、材料和腐蚀余量、船体外形参数、冰载荷、冰区总强度、冰区构件尺寸以及结构设计细则的具体要求;总结了各种规范体系的特点,为今后极地破冰船的结构设计研发提供了规范参考,具有一定的现实意义。

Having compared and analyzed the structural design rules for icebreaker ships that proposed by major classification societies, the paper investigates the different rules' specific requirements of the definition of ice classes, division of ice strengthening region, allowance of material and corrosion, parameter of hull shape, ice loads, the overall strength of ice zone, the scantlings of the ice-strengthening structures and the details of the structural design. The characteristics of the different rule systems are summarized to provide references for the structural design of the polar icebreaker ships, which has certain practical significance.
