State-Dependent Volume Change during Creep in Engineered Silty Sand

Park, Ka-Hyun / Chung, Choong-Ki / Jung, Young-Hoon

To investigate the volumetric creep behavior of engineered sand containing nonplastic silt, a series of creep tests was performed under various stress conditions and initial void ratios. It was found that contractive or dilative volumetric creep behavior was determined by a specific combination of the void ratio ( $e_{c}$ ) and the mean normal effective stress ( $p_{c}^{'}$ ) at the beginning of creep. Based on the experimental results, the range for which no volumetric change occurs during creep was determined, and this group of specific combinations of $e_{c}$ and $p_{c}^{'}$ was defined as the zero-creep volume change zone (ZCVZ). The contractive or dilative volume change pattern during creep can be predicted by the positions of $e_{c}$ and $p_{c}^{'}$ relative to the ZCVZ on the $e - \log p^{'}$ plane. The creep mechanism of the observed volumetric behavior was explained by adopting the microscopic mechanisms of dislocation slip and the recovery process in the creep of metals.
