Static Properties of Silty Soil Subjected to Repeated Freezing and Thawing

Abstract:

In order to deeply comprehend the static properties of silty soil subjected to repeated freezing and thawing in deep seasonal frozen area, the static properties were studied on silty soil under different freeze-thaw cycles, coefficient of consolidation, water content and confining pressure. The results showed that stress-strain relationship of silty soil was work-hardening, and mainly in a ductile failure state. Correlation analysis results showed that there were good relationships between static properties, such as static modulus and static strength, and freeze-thaw cycles, coefficient of consolidation, water content and confining pressure. The cohesion decreased with in creasing of the number of freeze-thaw cycles, but there was no changing law for the internal friction angle.
