Cyclic creep of frozen soils
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 conte...
