摘要
A procedure is presented for numerical modeling of processes that occur during deep seasonal freezing of soils by the finite-element method. The thermophysical problem is solved using heat-conduction equations with allowance for phase transformations of the water in the negative-temperature interval for a nonstationary thermal regime in three-dimensional soil space, and with consideration of moisture migration toward the freezing front. Knowing the distribution of the total moisture content in each time period of negative temperatures, it is possible to predict the magnitude of frost-induced deformations. © 2004 Springer Science+Business Media, Inc.
