Abstract: An attempt has been made to generalize the data on the dependence of the mechanical properties of ice on its structure which, in turn, is governed by the conditions of ice formation and existence. The influence of ice structure on its deformation and failure mechanism as well as on creep parameters, strength characteristics and adhesion forces has been shown. Three stages of recrystallization of polycrystalline ice during creep processes, namely crystal growth relative structure stabilization and crushing, have been pointed out. It is proposed to use the obtained dependences for forecasting the ice strength based on the conditions of ice formation and for changing the ice mechanical properties by ensuring adequate thermodynamic conditions during ice formation.
