Abstract

In this paper the results of a stress-deformation parametric analysis are presented to show the effect of an artificial non-expansive replacement layer over an intact expansive soil on the heave at the surface. Finite element code SV Flux and SV Solid are used to perform the stress-deformation analysis. Climatic boundary conditions for a semi arid region are used. Significant decreases in the heave amount were noted, depending on the thickness and soil type of the replacement soil.
