On accounting of mechanics of ice destruction when its testing on the contact strength
The researches demonstrated that the mechanics and picture of ice destruction during the real impact of the ice field on the vertical support of the structure are identical to all parameters characterizing the process of ice destruction in the massif at its testing by the method of the rigid sphere implementation. It gives the grounds for application of the power destruction concept in the calculations of the ice load on the elements. This concept is declared the specific energy of the mechanical ice destruction ε cr as a destruction criterion. That is determined by this method. The goal of this work is the presentation of the parameter research results of this physical and mechanical characteristic of the ice strength to update the normative document on designing of the ice-resistant structures.
