Publication details: Hanover, NH Cold Regions Research & Engineering Laboratory, 1995; CRREL report 95-12, Description: 39 sSubject(s): Online resources: Bibl.nr: VTI P0109:95-12Location: Abstract: 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 thoseparameters that calculate the hydraulic conductivity have the greatest influence on the variability of predicted heaving pressure.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.
