Water and heat interact in the process of freezing for the saturated soil.
And for the salinized soil, water, heat, and salt interact in the freezing process, because salinized soil has soluble salt.
In this paper, a one-dimensional mathematical coupled model of hydraulic-thermal-salt is established.
In the model, Darcy’s law, law of conservation of energy, and law of conservation of mass are applied to derive the equations.
Consider that a saturated salinized soil column is subjected to the condition of freezing to model the moisture migration and salt transport.
Both experiment and numerical simulation under the same condition are developed in the soil column.
Then the moisture content and salt content between simulation and experiment are compared.
The result indicates that simulation matches well with the experiment data, and after 96 hours, the temperature distribution becomes stable, freezing front reaches a stable position, and a lot of unfrozen water has time to migrate.
Besides, the excess salt precipitates when the concentration is greater than the solubility, and the precipitation is distributed discontinuously.
These results can provide reference for engineering geology and environmental engineering in cold region and saline soil area.
