Summary: | Results for creep tests during uniaxial, unconfined compressive loading of a frozen silt at -9C, a frozen sand at -8.5C and two other frozen sands at -9C are presented. Results of creep recovery tests on a frozen silt and a frozen sand are also reported. In order to elucidate soil behavior for modeling long-term creep deformation, the data are analyzed in terms of stress-strain behavior at constant times. The stress-strain behavior prior to tertiary creep is best represented by bisectional relations, instead of the usual continuous relations. Equations are presented for modeling the creep behavior for a single application of a constant load. |
