Shallow slump is a kind of geological disaster of expansive soil slope which is inevitable under the action of atmospheric dry-wet cycle,which often brings great trouble to the engineering construction in expansive soil area.In order to explore the true strength of expansive soil under specific boundary conditions,this article conducted the conventional saturated slow-shear test of Baise expansive soil under low stress and dry-wet cycle condition, compared and analyzed the anti-shear strength parameters obtained from the fitting of Mohr-Coulomb...
