Heave and Heaving Pressure in Freezing Soils: A Unifying Theory
A unifying theory is presented for the process of heave in freezing soils. Out of the Cold Regions Research and Engineering Laboratory (CRREL) school of D.M. Anderson came the concept of the segregation potential . Out of the Cornell school of R.D. Miller came the model for the heave rate . Here ide...

A unifying theory is presented for the process of heave in freezing soils. Out of the Cold Regions Research and Engineering Laboratory (CRREL) school of D.M.

Here ideas from both schools are put on a fundamental thermodynamic footing, leading to the definition of a new heave index . Both schools use the temperature gradient in the frozen fringe as the driving force for heave. We argue and demonstrate that this choice leads to erratic results.
