Comparative study on mechanical performance of silty soil and expansive soil below canal structures in cold regions [PDF]
HeliyonSilty soil was widely used as filling soil materials for the replacement of expansive soil in cold regions. This paper presents a straightforward approach for the effects of wetting-drying-freezing-thawing cycles on mechanical behaviors of silty soil and
