摘　　要：介绍了海冰离散元模型的建立过程,通过模拟海冰与结构相互作用的过程来研究冰载荷的作用规律,并探讨海冰速度、海冰厚度以及结构直径对结构所受冰载荷的影响。结果表明,离散元方法可以较好地表现海冰破碎形式并能准确预测冰载荷,且冰载荷与3种影响因素都为正相关关系,其中海冰厚度对冰载荷的影响最为明显。The establishment process of sea ice discrete element model is introduced.The action law of ice load is studied by simulating the interaction process between sea ice and structure.The influence of ice velocity,ice thickness and structure diameter on ice load is discussed.The results show that the discrete element method can well represent the breaking form of sea ice and accurately predict the ice load.The ice load is positively correlated with the three influencing factors,among which the sea ice thickness has the most obvious effect on the ice load.
