Détermination des caractéristiques physiques et mécaniques de l'argile molle de Tunis

Abstract : The objective of this work is to study the behavior of soft clays in Tunis and the determination of relevant physical and mechanical characteristics. Indeed, the identification of physical, mineralogical, sedimentary and mechanical parameters on the one hand and the study of the behavior of soft clay in Tunis, on the other hand, have allowed us first to estimate such level of meta‐stability. A physical model for the development of the sensitivity in Tunis soft clays has been developed. On the basis of the classifications suggested by several authors, and in order to assess the sensitivity of Tunis soft clays, a divergence of results was shown. Thus a specific classification for the Tunis soft clays has been proposed. In a second phase the study of behavior of Tunis soft clays allowed to confirm sensitivity of these clays, then to find the impact of the sensitivity on the (triaxial and oedometric) behavior of such clay type. Finally a study of the range of validity of the pressuremeter test in these Tunis soft clays demonstrated a significant underestimation of the initial shear modulus, going out from this testing procedure.
