Viscous Effects on the Stress-Strain Behavior of Gravelly Soil in Drained Triaxial Compression

In this study, the viscous properties of gravelly soil were investigated using a series of special drained triaxial compression tests with a large-scale triaxial apparatus. To evaluate loading rate effects on the stress-strain behavior, the axial strain rate was changed stepwise during otherwise monotonic loading (ML) at a constant strain, which resulted in a sharp increase or decrease in the deviator stress. Drained creep loading tests were also performed at several deviator stresses during otherwise monotonic loading and unloading along different stress paths. Findings show that the amount of creep strain increased with an increase in the deviator stresses. The stress-strain behavior was nearly elastic for some stress range immediately after ML was restarted at a constant strain rate following each creep stage. Viscous properties were very similar for both partially and fully saturated specimens.
