【 摘 要 】

It is known that when a submerged body moves under the ice surface in an ice cover, a system of flexural-gravity waves (FGW) appears, with a certain intensity of which it is possible to achieve partial or complete destruction of the ice. There are many theoretical works in which the submerged body is modelled in various ways, the influence of physicomechanical properties, the depth of immersion and the length of the body on the stress-strain state of the ice cover is analysed. Similar works of an experimental nature are practically not encountered. An experimental study of the influence of the relative elongation of a submerged body and the depth of its immersion in under-ice motion on the deflection and curvature of the generated flexural-gravitational waves is performed. With the help of the proposed criterion of ice destruction, the ice-breaking capacity of the FGW was assessed.
