基于国际船级社协会极地冰级规范，研究了冰载荷计算公式，从挤压力计算、船冰作用工况、冰压力-面积关系、船级因子及船体区因子等方面研究了规范的理论基础。基于目前极地发展现状，本文分析了开展极地水面舰船规范研究的必要性，在分析现有国际船级社协会极地冰级规范不足的基础上，提出了极地水面舰船冰级规范的研究方向。
The formula of ice loads is introduced based on International Association of Classification Societies polar class. The theoretical basis of the rules is studied in terms of the calculation of normal force, the ice-ship interaction form, the crushing pressure-contact area ralationships, class factors and hull area factors. Considering the present situation of Arctic shipping and Arctic development, the necessity of conducting a research on the rules of polar surface naval ship is presented. The shortcomings of the existing rules are validated. Finally,the direction of the rules of polar surface naval ship is pointed out.
