According to thecharacteristics of sea-ice in Bohai, the mechanism of ice breakup ontidal fluctuation and waves is analyzed, and the physical model testsare carried out to confirm the rupture theory model of ice sheet underthe action of regular waves.

• 本文根据渤海海冰的特点，分析了海冰在潮汐和波浪作用下的断裂机理，并通过物理模型实验验证了在波浪作用下海冰断裂理论的可行性。
