Creep of Frozen Silt and Clay.
Abstract
Unconfined compressive creep strengths and strains were measured for remolded saturated frozen Hanover silt and Suffield clay. The creep tests were conducted at the approximate stress levels of 60, 35, 20 and 5% of the conventional unconfined compressive strength. Testing temperatures were 15, 25, 29 and 31F (-9.45, -3.89, -1.67 and -0.56C). It was found that the variation of unconfined compression peak strength with temperature can be represented by Sigma sub p = Alpha(Theta/Theta sub 0) to the (0.5) power. Unconfined compression creep strength can be estimated by Vialov's strength equation. Long-term creep strength is less than 45% of unconfined compression strength and can be as low as 10% of this strength. (Modified author abstract)
