Popis:	In the paper the mechanism of the conservation of the ice cover bearing capacity under the influence of transverse loads if there are cracks in it was considered. Experimental and theoretical study of the main aspects of this mechanism was performed on the ice beams obtained by sawing two parallel wide slits in the ice cover. At its ends, the beam was one with the entire ice plate. The obtained diagrams of beam failure made it possible to interpret cracks as hinges connecting separate blocks of ice cover in the lines of their axes. The finite element method for the subsequent evaluation of the proposed method of accounting for interaction on the crack faces was used. The research results can be used in the mathematical model making of the ice deformation and ice failure taking into account cracking, as well as in the development of simulation mode of ice cover.
