Abstract: In this paper, on the basis of the former experiments on the mechanics of ice, a mathematical model relatively consistent with the actual state of oceanic ice is established. According to this model, the constitute relation is derived and compared with the experiment of uniaxial anti-pressure intensity. The maximum anti-pressure intensity formula is established which describes the relations between compressive strength and strain rate of oceanic ice. This curve and other scholars have made the biggest test compressive strength and strain-rate trends in the relationship between the curves match that this formula is correct. This formula for the structure of the anti-ice oceans provide a theoretical basis for calculating.
