520 3# ‡aExtends and modifies approximate analytical technique of Gilpin (1980) to account for effects of distributed phase change in both heat- and mass-transfer components of formulation. Approach requires, as input, relationship between frozen hydraulic conductivity and temperature, and predicts discrete location of each ice lens within freezing soil. Solution can be carried out quickly on microcomputer to obtain heave, suction at frost front, ice-lens temperature, and other results of interest with time. Method predicts effects of changing overburden pressure on predicted heave rate. Proposes method of extracting input parameters for discrete ice-lens procedure from series of frost-heave tests. Theory has been tested and calibrated against published frost-heave test results.
