CREEP OF SAND-ICE SYSTEM

Unconfined uniaxial creep tests were conducted at -8.5 degree C on sand-ice samples with an average wet density of 124 pcf (1,986 kg/m3). The samples were 94% water saturated, on the average, prior to freezing. Thus the data represent the behavior of slightly undersaturated frozen sands. Stress-strain data for different durations of loading were obtained by replotting the creep data. Values of the stress characterizing the change in stress-strain relations are confirmed by creep rate-stress data. It is shown that use of a single continuous stress function to represent stress-strain data in models must be limited to either stresses greater than, or less than, the limiting long-term strength. A single continous stress function cannot represent realistically the entire stress range. /ASCE/
