摘要
通常情况下，作用在斜体结构表面的冰力小于垂直结构，因此斜体结构成为有冰海区海洋结构的优选结构，冰对斜体结构作用力学机制的分析是近些年来国际上研究的热点问题。本文运用简单的二维理论及较为复杂的三维理论，依据辽东湾环境条件，采用计算与作图分析的手段，对摩擦系数、坡角、冰强度及冰厚如何影响作用在斜体结构上的水平冰力进行了讨论。
It is well known that the ice forces on structures can be reduced by providing a sloping plane instead of a vertical face. The sloping structures are popular in defeating ice encounter. Many efforts have been made in the last twenty years to further study the interaction of sea ice with the various types of the sloping offshore structures. This paper deals with the ice interaction with the sloping structures by the two and threedimensional theory. The effects of the principal parameters which include the friction coefficient, slope angle, ice strength and ice thickness in Laodong bay of act on the sloping structures were discussed.
