CREEP OF FROZEN SANDS

UNCONFINED COMPRESSIVE CREEP STRENGTHS AND STRAINS WERE MEASURED FOR FROZEN SATURATED OTTAWA SAND (20-30) AND MANCHESTER FINE SAND. THE CREEP TESTS WERE CONDUCTED AT APPROXIMATE STRESS LEVELS OF 60, 35, 20 AND 5 PERCENT OF THE CONVENTIONAL UNCONFINED COMPRESSIVE STRENGTH. TESTING TEMPERATURES WERE 15, 25, 29 AND 31 F. IT WAS FOUND THAT THE UNCONFINED COMPRESSIVE CREEP STRENGTH OF THE FROZEN SAND CAN BE PREDICTED USING VIALOV'S STRENGTH FORMULA AND THAT CREEP STRAIN CAN BE PREDICTED USING TWO SHORT-TERM, HIGH-STRESS- LEVEL CREEP TESTS. EQUATIONS ARE GIVEN TO PREDICT TOTAL STRAIN. FOR STRESSES BELOW THE LONG-TERM STRENGTH, THE STRAIN RATE IS DIRECTLY PROPORTIONAL TO THE RECIPROCAL OF TIME DURING STRESS ACTION UNTIL COMPLETE STABILIZATION OCCURS. /AUTHOR/
