Frost Heave Forces

Frost Heave Forces

(OP)

Does anyone know how to calc. the resulting forces from the expansion of Ice?  I'm a recent grad (bachlor deg.) and I find that people in "the real world" would rather just call out on the plans to replace the material under the footing or foundation with a more suitable material for drainage, or just lower the footing below frost depth. Ecconomically these might be the better options, but I still would like to know, for my own knowledge.

Thanks.

RE: Frost Heave Forces

There isn't a definite expansion force that I'm aware of; there's too many variables.  Ice can have about 30 different states.

The force of expansion, however, can approach 2000 psi.
