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.
