Experimental study on the micro-fabric of frozen sediment using triaxial deformation and computerized tomography

The micro-fabric of frozen sediment was studied using a triaxial deformation machine with computerized tomography (CT) to describe a quantitative relationship between microstructure and mechanical behaviour at different temperatures and confining pressures. Micro-fabric changes were described by CT images and CTvalues. Relationships between CT values and the stress-strain curves were analyzed. It was shown that CTvalues can describe the deformation quantitatively.
