Unfrozen water content affects thermal-hydro-mechanical characteristics of frozen soil

The content of unfrozen water in frozen soil affects the freeze-thaw cycle, hydrological cycle, water and energy exchange between land and air, vegetation growth and structural strength of soil in cold regions. Currently, theoretical explanations for the presence of unfrozen water include capillarity action, surface effect, adsorption forces and the electrical double layer.
