Etude du tassement différentiel sur sols hétérogènes

ABSTRACT The relative settlements are a frequent source of disorders in structures. Their origin often lies in space variability of the properties of the grounds, whose imperfect taking into account harms the forecast of these settlements. We present the first results obtained from the finite elements code Cast3M on the problem of a single shallow foundation and of two neighbouring shallow foundations laying on a heterogeneous elastic ground. The space variability of the ground properties is modelled using the rotating stripes theory and a Monte-Carlo method.
