摘　　要：位于寒冷海域的海工结构物,冰载荷往往是控制载荷之一。合理地选取结构物工作海域的环境条件和冰的物理力学特性,直接关系到结构物的设计、使用和安全。本文分析讨论了在设计寒冷海域结构物时,考虑冰载荷的影响、海冰物理力学特性对冰载荷的影响以及计算冰载荷的公式选用和有关参数的选取。对可能作用在结构物上的各种冰载荷的计算进行了分析,提出计算这些冰载荷的一些看法和建议。Usually, action of sea ice ajainst offshore engineering structure is one of the dominative loads in cold waters engineering structure design. The reasonable selection of environmental condition and ice physical mechanical properties in the region are direct relating to the structure design, operation and safety. In this paper, the sea ice force acting on the structure, the ice physical mechanical properties and the parameters selecting in calculation equation proposed by API(RP2N)and others are discussed. Some ideas are considered and proposed to the various kinds of ice loads acting on the structure when some formulas are used to calculate.
