ABSTRACT: Soils can be considered as viscoelastic materials having an intermediate behavior between Newtonian fluids and the perfectly elastic bodies. This type of behavior is the basis of the birth of rheology which studies the flow, deformation and viscosity of materials under external stress taking into account its speed rate. Haiti is a country where seismic risk is very high. It is therefore important to study dynamically the mechanical properties of soils. This paper presents how rheology has been used to study the deformation and structural collapse of marl samples of the "Morne Delmas" geological formation in Haiti.

RÉSUMÉ: Les sols peuvent être considérés comme des matériaux viscoélastiques ayant un comportement intermédiaire entre les fluides Newtoniens et les corps parfaitement élastiques. Ce type de comportement est à la base de la naissance de la compte de les propriétés mécaniques des sols de façon dynamique. Cet article présente la façon dont la rhéologie a été utilisée pour étudier la déformamarnes de la formation géologique « Morne Delmas » en Haïti.
