中文摘要：

理论分析和数字模拟被用于在冰 rafting 上研究波浪，水流和风的效果。分析结果证明那个波浪是为冰骨折的关键因素。冰 rafting 的过程用分离元素方法被模仿。模仿的结果证明失真或弯曲破裂第一发生，然后由冰 rafting 列在后面。冰是的包括地分析的结果表演容易，在波浪，水流和风的同时性行动以后的 rafted，和波浪斜面的行动被忽略。而且， rafted 冰长度与海洋电流和风的增加的力量增加。

英文摘要：

Theoretical analysis and numerical simulation have been applied to researching the effect of wave,current and wind on the ice rafting.The analytical results show that wave is the key factor for ice fracture.The process of ice rafting is simulated using the discrete element method.The simulated results show that the distortion or flexure breakage happens firstly,then followed by ice rafting.The comprehensively analysed results show that the ice is easily rafted on the simultaneity action of wave,current and wind,and the action of wave can＇t be ignored.Moreover,the rafted ice length increases with the enhancive force of ocean current and wind.
