Conference paper


A shallow, circular, rigid and rough foundation model instrumented with eleven normal and tangential stress cells equiped with electrical strain gauges is first detailed. Two loading tests corresponding to two densities of the soil (Sand of Hostun) are then presented. Results of the interaction soil-structure and stresses and deformations in the mass of the soil are precised and analysed and the influence of the density is pointed out.

A numerical model using the finite element method with T3 elements and axisymetrical geometry is then presented. The soil behavior considered is an isotropic hypoelasticity, function of the stress level. The incremental non linearity is solved by a classical initial stress method. Two extremal cases were calculated: smooth foundation and a rough one. Comparison with experimental results are analysed.
