Abstract

Abstract

Sea ice strength, as one of the most important mechanical parameters affecting the macro-deformation characteristics and micro-failure features of sea ice, plays a significant role both on sea ice dynamics of geophysical scale and ice load of offshore structures. In this study, sea ice mechanical and physical parameters of the Bohai Sea were measured in field and laboratory tests. The relationships between sea ice strengths and the brine volume and stress rates are analyzed based on the experimental data. The results demonstrate that the exponential function can express the relationship between the sea ice strengths and the square root of brine volume, while the linear function is perfect for the relationship between sea ice strengths and the stress rate. Finally, the unified representation of sea ice strengths under the influences of brine volume and stress rate is established. This present work can be benefit for the determination of sea ice strength in the engineering applications.
