本文根据多年环渤海海冰弯曲强度试验结果，分析了诸单因子对海冰弯曲强度的影响，并给出了各海区海冰弯曲强度设计值。海冰的弯曲强度随着应力速率的增加，经过延性、过渡和脆性三个阶段，在过渡区，海冰的弯曲强度达到最大值。随冰温的降低和冰中盐水体积减少，海冰的弯曲强度增大。
According to the test results of sea ice bending strength over the years in the Bohai Sea, this paper analyzes the effect of single factor on the bending strength of sea ice, and gives the design values of sea ice bending strength in each sea area. The flexural strength of sea ice increases with the increase of stress rate. After ductility, transition and brittleness, the bending strength of sea ice reaches the maximum in the transitional zone. With the decrease of ice temperature and the decrease of brine volume in ice, the bending strength of sea ice increases.
