| 摘 要： | 海冰荷载是结冰海区海洋工程结构物设计的控制荷载，当结构物迎冰面具有倾斜表面时，海冰将发生弯曲破坏，从而大大降低海冰荷载值。本文针对一个单位宽度的简单斜坡结构物，分析冰板作用于斜坡结构时的破坏机理，提出基本假定，建立一个通用的二维计算模式，并对给定的工程结构物的海冰设计条件进行海冰荷载计算，给出了作用于斜坡结构上的冰荷载值。

| Abstract: | A simple inclied structure with unit width was taken into account to discuss the failure mechanism of the ice sheet acting on the inclined structure.Asupposition was proposed, and a general two-dimensional model has been established. Then,the calculation of sea ice force was carried out for given engineering structure and designed conditions of the sea ice, The calculating result of sea ice force acting on the inclined structure was given. |
