| 摘 要： | 回顾了解决海冰引起结构振动分析方法的要求，通过室内冰力模型试验得出了冰激振动的重要参数－冰力频率，幅值的特性。研究表明，在低冰速时，冰力频率与冰速对冰厚之比呈线性关系；高冰速时，冰力步与冰速对冰厚之比呈现恒定性，文章还根据试验数据以及统计分析，推荐了冰力幅值计算公式和取值范围。

| Abstract: | Reviewed in this paper are the main points of various methods for solving the ice-induced structural vibration. Through indoor ice force model experiments, the characteristics of ice force frequency and amplitude are obtained. The study indicates that at a lower velocity,ice failure characteristic frequency has a linear relationl ship with the increasing ratio between velocity and thickness; and at a higher velocity,the relation is invariable between them. And the calculation formula and amplitude arrange of ice force are recommended based on experimental and statistic data. |
