Effects of wetting-drying-freezing-thawing cycles on mechanical behaviors of expansive soil

Cyclic action of wetting-drying-freezing-thawing (WDFT) is an important factor for damages of canals in seasonally frozen regions, which should be taken into account for relevant studies. This paper presents details of an investigation dealing with the effects of wetting-drying-freezing-thawing cycles on the mechanical behaviors of expansive soil by triaxial tests. The results show that the WDFT cycles had a significant impact on the attenuation...
