Macro-meso failure mechanism and strength criterion of frozen weakly cemented sandstone under triaxial unloading

Macro-meso failure mechanism and strength criterion of frozen weakly cemented sandstone under triaxial unloading

IntroductionIn the excavation engineering of tunnels and mines in the western cold region, the unloading failure zone is mainly caused by stress release. This study aimed to investigate the deformation and failure mechanism of frozen weakly cemented sandstone (FWCS) when the initial principal stress...
