Abstract: Ice formation in enclosed cavities is possible both under natural conditions and due to water freezing inside engineering structures. A specific feature of this restrained freezing is that it causes an increase in the hydrostatic pressure because of an abrupt drop of the water density associated with the transition from the liquid phase into the solid one. This rise in the pressure of the water core deforms or breaks natural or artificial walls of the cavity. Physical properties of the sea ice, including the density, are pronouncedly different from fresh ice properties because the sea ice contains a liquid phase: the brine. the salinity of the ice directly affects its density, and therefore the water core hydrostatic pressure in case the entrapped seawater freezes. This paper presents a theoretical study of the process and the aim of this investigation was to see whether accounting for the salt could refine results obtained in (Pekhovich, 1983).
