Resumo

Frost heaving of soils is the main cause of engineering accidents in cold regions, but the current experimental as well as numerical studies focus on frost heaving deformation of soils, while there are fewer numerical studies on the main factors causing frost heaving deformation: pore water pressure. In this study, new calculation formulas of pore water pressure for saturated frozen soil are obtained by solving Gibbs free energy equation, and a thermo-hydraulic coupling model under different boundary conditions is constructed to calculate the pore water pressure values and water flow during water migration process. The results showed: (1) the pore water pressure of freezing soil with the ice lens is about ten times that without the ice lens, and the calculated results agree with the previous known experimental results; (2) The temperature of the cold end directly determines the upper limit of the pore water pressure value of freezing soil; (3) Pore water pressure decreases with depth much faster than the rate of temperature decrease.
