ABSTRACT: The work presented in this article relating to the study of the behavior of swelling soils of Diamniadio has set itself the objective of modeling the shrinkage-swelling of crumb marl, foliated at-tapulgite marl and sandy clay. to limestone concretion using the method based on the elastic modulus (MEBM) presented by Adam and Vanapolli (2013) [1]. This method, which focuses on soil-atmosphere interaction, makes it possible to predict changes in soil volume as a function of climate variation. In this study, soil swelling shrinkages were well estimated taking into account the associated suction and elastic modulus as key parameters. The latter are used in a constitutive relation for the change in volume which is based on the mechanics of unsaturated soils developed by Fredlund and Morgenstern (1976) [2]. This method is based on the two-dimensional software (VADOSE/W) which uses climatic data, the soil profile and their physical and geotechnical characteristics to determine variations in suction, an essential parameter for calculating vertical movements of the soil in the time.
