BASIC CONCEPTS OF FROST HEAVING.

Summary

PRESENT KNOWLEDGE CAN BE USED TO QUALITATIVELY ESTIMATE FROST-HEAVE EFFECTS, TO MINIMIZE THE POSSIBILITY OF DAMAGE, AND TO EVALUATE TECHNIQUES FOR CONTROLLING FROST HEAVING. THIS DISCUSSION IS CONCERNED WITH HEAVE CAUSED BY WATER THAT IS DRAWN TO THE FREEZING REGION AND FROZEN (OPEN-SYSTEM HEAVING), RATHER THAN WITH THE FREEZING EXPANSION OF WATER THAT WAS INITIALLY IN THE SOIL (CLOSED-SYSTEM HEAVING). THE EFFECTS OF SOIL PARTICLE SIZE, HEAT AND WATER FLOW RATES, AND OVERBURDEN PRESSURE ARE DISCUSSED. MODELS ARE DISCUSSED. THE RATIONALES OF TECHNIQUES FOR CONTROLLING FROST HEAVING AND SEVERAL CRITERIA FOR ASSESSING THE SUSCEPTIBILITY OF SOILS TO FROST HEAVING ARE DISCUSSED.
