The paper presents the results of studies of the features of deformation and destruction of the ice cover affected by a close underwater explosion, as well as by horizontally installed cylindrical shells under the combined action of the explosion and hydrostatic pressure. The research is based on the results of computer simulation of the processes of underwater explosion and ice cover deformation. It is shown that the second pulsation of the bubble exerts a controlling influence on the nature and parameters of the deformation and destruction of the ice cover under the combined action of a close underwater explosion and a large hydrostatic pressure on the shell. The dependence of the ice explosion resistance on the depth and power of the charge is determined. The influence of the main physical parameters of ice on the explosion resistance is revealed. The results of the research can be used for creating structures effectively resisting the effects of a close underwater explosion.
