RESULTS FROM A MATHEMATICAL MODEL OF FROST HEAVE
A one-dimensional model for simulation of frost heave in a vertical soil column is presented. The model is based on simulatneous computation of heat and moisture transport in a freezing or thwing soil. Thermal processes at the freezing front are approximated by a lumped isothermal approach. The model accurately simulates frost heave, soil pore-water pressures, and temperatures when compared with a laboratory freezing column; however, to achieve adequate correlation certain model parameters must be determined by calibration. Because the model, like the frost-heave process itself, is highly sensitive to environmental and soil parameters that are variable in both time and space, purely deterministic simulations will not provide sufficiently accurate predictions. Consequently, further development of the model is required in order to include a statistical-probabilistic approach for estimating frost heave within specified confidence limits. (Author)
