STRESS-STRAIN RELATIONSHIP OF FROZEN SAND AS A COMPOSITE GEOMATERIAL

摘要

The present paper aims at developing a simplified model for a stress-strain relationship at small strains up to an ini- tial yielding of homogeneous saturated frozen sand. The modelling of elastic moduli for an ice-sand mixture as a com- posite geomaterial is first introduced based on previous studies, where a saturated frozen sand is treated as the ice- sand mixture. The applicability of modelling the elastic moduli under constant temperature is then discussed from the theoretical and experimental points of view.
