摘要
对无限长冰层覆盖水域下波动的弥散方程进行了简化,利用波能通量法计算了波浪传入冰层覆盖水域后的变形,讨论了考虑冰层的弹性位能对计算波浪进入冰层覆盖水域后波高变化的影响,得到了无量纲参数T2^(1/g/d),与波高变化比值H_i/H的曲线,分析了入射周期T,水深d,冰厚h_i等对冰层内应力的影响。
The dispersion equation of wave motion in a water field covered by ice with infinite length was simplified. The calculation of wave deformation when the wave transports into ice-covered water by using the method of energy flux was introduced. The effect of ice sheet's elastic potential energy against the change of wave amplitude was analyzed and the related curve of dimensionless fraction T ,D/pgd4 and Hi/H was obtained. The main effects of incident wave period T, water depth d and ice thickness h to the ice stress were also analyzed in this paper.
