| 中文摘要: |
| 浅海区采油平台常采用斜坡式人工岛形式，以降低冰力作用。但海冰沿着斜坡上爬至平台并形成堆积，同样会对平台设施造成破坏，因此有必要对海冰堆积爬坡的关键参数进行的研究。利用模型冰模拟海冰的堆积和爬坡过程，分析了模型冰爬坡和下滑角度、最大堆积高度等的关键参数以及模型冰断裂长度的统计特性及其与变形模量的关系。 |
| 英文摘要: |
| Sloping artificial islands are mostly applied at oil platforms in shoal regions. Although there is a reduction of ice forces of sea ice on platforms, damage inevitably occurs when ice ride up to the platforms along the slopes. It is necessary to study the main parameters of sea ice ride-up and pile-up. Laboratory model tests with are conducted to simulate the process of ice ride-up and pile-up. Climbing angle, sliding angle, break length of ice sheets and the maximum height of climbing-up, and the correlation between break length and elastic modulus were discussed. |
