摘要: 本文在海冰试验研究的基础上,建立了一个比较符合实际状态的海冰的数学模型。并根据此模型推导出海冰的本构关系,通过抗压强度试验来验证了所建立的本构关系的正确性。根据推导出的海冰的本构关系拟和出海冰的最大抗压强度和应变率的关系曲线,从而导出海冰最大抗压强度和应变率的关系的公式。这个曲线和其他学者所做试验得到的最大抗压强度和应变率的关系曲线变化趋势相吻合,说明此公式的正确性。此公式能为海洋结构的抗冰计算提供理论依据。

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.
