摘　　要：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。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。全文包括辽东湾冰厚特点、以辽东湾海冰力学性质参数为依据的分析计算结果和结合多年海冰调查结果的讨论。Multilayer rafted ice is a characteristed ice type in Liaodong Bay and results from the interactions of marine environmental dynamics.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.The ice thickness characteristics in Liaodong Bay,the analytical results on the rafted ice based on Liaodong Bay ice mechanical properties and the discussions on the comparison of theoretical and insitu investigation results are given.
