Static properties of modified soils influenced by freezing and thawing

Abstract

The static properties such as stress-strain relationship for cement-and lime soil subjected to freezing and thawing cycles are researched. The results show that stress-strain relationship of cement soil is work-softening, and is mainly in a brittle failure state. While the stress-strain relationship of lime soil turn into work-hardening, and is in a ductile failure state. The improvement effect of cement is superior to lime under repeated freezing and thawing.
