摘要
海冰物理力学特性是冰区海上结构物强度设计的一个重要准则,只有合理选用海冰物理力学特性值,才能使冰区海上结构物的设计更加经济合理。而海冰是一种性质极其复杂的天然材料,其物理力学特性受冰温、冰盐度以及它的晶格结构、受力方向、加载速率等诸多因素的影响。在不同气候环境条件下海冰具有不同的形态,有平整冰、重叠冰、堆积冰、冰脊、冰山等形态。不同海冰形态、不同的地区、不同的气候、不同的海水的盐度、不同的海冰内盐水体积、不同的光照时间等因素都会导致不同的海冰物理力学特性。
The physical and mechanical properties of sea ice is an important criteria for sea ice physical strength structural design,only the rational choice of the value of physical and mechanical properties of sea ice to make ice offshore structures design more economical and reasonable. The sea ice is an extremely complex nature of natural materials,its physical and mechanical properties affected by ice temperature,ice salinity and its lattice structure,the force direction,the loading rate and many other factors. Climatic conditions in different sea ice has a different shape,there are smooth ice,overlapping ice accumulation of ice,ice ridges,icebergs and other forms. Different ice forms,different regions,different climate,different salinity of seawater,sea ice in different brine volume,different illumination time and other factors will lead to different physical and mechanical properties of ice.
