| 摘 要： | 为减轻海冰对斜坡人工岛的灾害性影响,经过现场调查和分析,揭示了由于大面积冰盘的能量使其一部分与斜坡人工岛发生作用而产生爬坡、破坏和堆积现象,确定了斜坡人工岛前海冰堆积体的形状.现场调查和物理模型试验结果表明,采用曲面破冰结构诱导海冰在斜坡人工岛前形成堆积体,可以增加海冰接触人工岛的能量消耗,降低海冰对斜坡人工岛的危害.

| Abstract: | Sea ice can make disastrous effect on man-made slope island.The paper revealed that the large floe energy was focused and partly interacted with man-made slope island,and the floe broke,climbed up and piled in front of man-made slope island.The authors put forward a new method to calculate the shape of sea ice pile-up.Field investigation and physical model tests have proved that the impact on the man-mad slope island from sea ice can be reduced by adopting the ice-breaking structure to induce the sea ice pile-up in the front of the slope island,because the sea ice pile-up needs more energy for sea ice to touch the island as a barrier. |
