<br/><br/> The first part of the present thesis concerns with performing a numerical simulation of the swelling pressure test to evaluate the effect of SWCC shape on the swelling pressure. The second part concerns with performing a simulation of the replacement method to evaluate its effectiveness on the heave. The effect of the building stiffness on the swelling deformation was also studied. The impact of increasing the building stiffness of the first two stories of the building on the swelling deformation was also studied. The influence of the replacement soil depth and the building stiffness on the differential upward movement in different stories of a building was investigated. The ABAQUS software and Regina clay are used in this analysis. The present results show that the swelling pressure increases with decreasing the initial water content and increasing the initial soil suction. Higher replacement soil stiffness increases the differential heave between footings
