重叠冰

辽东湾多层重叠冰单层厚度的理论分析

Theoretical analysis on the rafted ice thickness in Liaodong Bay

多层重叠冰是辽东湾海冰中特有的一种冰类型，它是海洋环境动力作用的产物。

Multilayer rafted ice is a characteristed ice type in Liaodong Bay and results from the interactions of marine environmental dynamics .

基于渤海海冰现场观测资料，分析了重叠冰的基本特征；

Based on the information of the field observation in the Bohai Sea , the basic characteristics of rafted ice are analyzed .

本文用力学观点阐明多层重叠冰的形成机制，介绍了弹性板壳压曲破坏模型。

In this paper , the forming mechanism of the multilayer rafted ice is described from mechanics view , and the buckling failure of a plate on an elastic foundation is introduced .

在相同冰厚条件下，指状冰的重叠长度约为一维重叠冰的1/2左右。

Under the same thickness of ice , the rafting length of finger ice is about one half of that of one dimensional rafted ice .
