The volume of frozen soil will change because of the moisture freezing or thawing. This is one of the main factors that make the destruction of the constructions in low temperature region. In this paper, an analysis model is given to simulate the freezing process of the frozen soil. By the use of FEM, the detailed deduction of the computational equations is given as well the iterative calculation process. Also, an example is presented to testify the validity and precision of the model.
