摘　　要：在海洋冰区中,沉箱(人工岛)在抗冰方面比传统的桩基式平台具有很大的优越性,但沉箱设置引起的海冰爬升和堆积也威胁它的有效利用。在详细分析了运动海冰与沉箱的碰撞、海冰的爬升和堆积全过程的基础上,建立了海冰相对于沉箱的爬升和堆积模式。Caisson has many advantages than the traditional platforms in resisting ice loads during offshore activities, but it will still face crisis when it is piled with ice severely. In this paper, ride - up and pile of sea ice against offshore conical structures are studied quantitatively. The main contribution of ride -up from wind,current, tide and wave et al. is discussed.
