摘要
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 testing results of the sea ice bending strengh in Bohai Sea for many years,the influence of each factor on the strength was discussed and the design values of the strength in each zone were given,The sea ice bending strength underwent three stages of strength transition and brittleness with the increase of the stress rate.At transition region,the sea ice bending strength reached the maximum value.The sea ice bending strength increased with the decrease of brine volume in the sea ice and the diminultion of the ice temperature.
