| 中文摘要: |
| 本文将海冰在斜坡式防波堤前的堆积过程简化为二维的动力学问题，假定海冰为粘弹性体，在多边块体运动模拟系统基础上，采用离散元数值方法对冰排爬升堆积过程进行了实时仿真模拟。通过与二维理论断裂模型及物理模型试验结果对比，证明了此数值模型的合理性与可行性。 |
| 英文摘要: |
| The pile up process of sea ice on inclined breakwater is simplified as a 2-D dynamic problem to establish the numerical simulation model.The ice is referred as viscous elastic material and the discrete element method is applied to simulate the whole process of pile up. The validity of the simulation is verified by physical modeling. |
