Frost Heave Calculation
Frost Heave Calculation
(OP)
Hello All,
I am trying to determine the frost heave that will be experienced on a spread footing for pipe supports. I would like to use piles to be able to mitigate the issue of heave. However, the client would like us to use foundations above frost depth. I am trying to determine the heave on this foundation to assure the diesel fuel pipes running on the supports can withstand the movement. I have done some research but am unable to find a formula to calculate the heave that is practical. All of the formulas either require laboratory testing or are calculated in a completely controlled environment.
Any suggestions?
Thanks!

Then again, I really don't know. I don't like the sound of the structural engineer wanting to use piles but the non-engineering-client requesting something else - something more risky!

Frost heave can easily be several inches in northern states with frost-susceptible (silty) soils and a shallow water table or just poor drainage. On the other hand, dry, clean, sand or gravel may freeze without heaving. Heave can vary a lot from year to year depending on moisture conditions and weather.
Tell us about your soil type, water table, and approximate location.

I think you'd have a couple options that are cheaper than driving pile. In general pile caps are placed below frost line anyway:
