Abstract
Cyclic creep behaviour of frozen saturated sand and frozen clays was studied by superimposing alternating stresses over a mean static compressive stress on the samples. Cyclic loading increased the creep rate of these materials considerably, which could be due to the increase in unfrozen water content generated by the transient thermal energy produced by mechanical cycling. The strain increment per cycle was found to increase with increasing strain in frozen sand, whereas it decreased in frozen clays, showing a tendency for strain hardening.
