Abstract In order to elucidate the phenomenon of freeze-thaw hysteresis and uneven frost heave in soil/rock mass during the freeze-thaw process，the mechanism of freeze-thaw hysteresis and freeze-thaw water migration was studied. Firstly，according to the generalized Clapeyron equation and Gibbs-Thomson equation，the freezing temperature equation of liquid water at any curved interface is given，and the freezing and thawing model of capillary is constructed. Based on this，by introducing the “main-branch type” pore structure with poor freeze resistance，the freeze-thaw hysteresis triangle model of capillary-film water is constructed. Finally，the correctness of the model is verified by low-field nuclear magnetic resonance experiments. The research shows that：(1) due to the difference in the curvature of the freeze-thaw boundary，the capillary pressure is twice the interface pressure，resulting in the melting temperature being only 1/2 of the freezing temperature；(2) the interface pressure is only related to the boundary conditions and has nothing to do with the freeze-thaw process. (3) The interface pressure has nothing to do with the theoretical ice pressure，theoretical suction，migration driving force and surface adsorption force，but is inversely proportional to the theoretical liquid pressure and the net suction；(4) Under the action of the interface pressure，the net suction is always maintained during the freezing and thawing process：PSuhi，1＜PSuhi，2＜PSuhi，3，thereby driving the migration，aggregation and phase transition of unfrozen water from micropores→secondary pores→main pores. In conclusion，the interface effect is the main cause of freeze-thaw hysteresis and freeze-thaw moisture migration.

Key words： soil mechanics freeze-thaw hysteresis freeze-thaw water migration capillary pressure interface pressure interface effect
