Abstract:A series of geotechnical centrifuge model tests were carried out to study the influences of alternation between drying and wetting on the deformation and stability of the expansive soil slope. The influences of cracks and infiltration on the stability of expansive soil slope were analyzed and the mechanism of the failure of expansive soil slope was investigated.
Keywords:expansive soil  alternation between drying and wetting  stability of slope  crack  infiltration of water  centrifuge model test
