13. ABSTRACT (Maximum 200 words)
A revised version of an earlier attempt to numerically solve Miller's equations for the RIGIDICE model of frost
heave is presented that corrects earlier mistakes and incorporates recent improvements in the scaling factors of
ground freezing. The new version of the computer code also follows the concepts of Object Oriented Numerics
(OON), which allow for easy modification and enhancements. Analysis of the program is accomplished with the
symbolic math program MathCad. A brief sensitivity analysis of the input variables indicates that those
parameters that calculate the hydraulic conductivity have the greatest influence on the variability of predicted
heaving pressure.
