In this paper, statistics of ice thickness and ice strength of first-year sea ice along the Northern Sea Route (NSR) is studied to provide useful information for the design and operation of Arctic ships. Specifically, ice thickness, ice strength and other physical parameters of the sea ice are estimated. Four representative sites are selected to study the ice environment and ice strength in different sea areas along the NSR during the ice growth season. Besides that, a good knowledge of the co-variation relationships between these ice parameters in a particular region would promote the estimation of ice loads acting on structures located in this region. In this work, a novel probabilistic model is introduced to describe the probability distribution of the ice flexural strength. The co-variation relationships between ice thickness and ice strength are quantified in terms of correlation coefficients. The influence of air temperature on ice properties is also investigated and discussed.

北海航线第一年冰层厚度和强度统计

本文研究了北海航线（NSR）沿线第一年海冰的冰厚和冰强度的统计数据，为北极船舶的设计和运营提供有用的信息。具体地，估计海冰的冰厚度、冰强度和其他物理参数。选取4个有代表性的站点，研究冰生长季节NSR沿线不同海域的冰环境和冰强度。除此之外，对特定区域中这些冰参数之间的协变关系的良好了解将促进对作用于该区域结构上的冰载荷的估计。在这项工作中，引入了一种新的概率模型来描述冰弯曲强度的概率分布。冰厚度和冰强度之间的协变关系根据相关系数进行量化。还研究和讨论了气温对冰特性的影响。
