Study on strength degradation and failure mode evolution of fractured sandstone under coupled freeze-thaw cycles and confining pressure

ObjectivesTo clarify the mechanical response of fractured sandstone under coupled freeze-thaw cycling and confining pressure conditions， the effects of freeze-thaw cycles and confining pressure on its mechanical properties and failure mechanisms were investigated.MethodsGray sandstone was selected a...
