Finite element implementation of a homogenized constitutive law for stone-column reinforced foundation soils, with application to the design of structures

Résumé

Making use of the homogenization method for periodic media, developed in the context of elastoplasticity, a simplified constitutive law is proposed for a stone column-reinforced soil, regarded as a homogeneous but anisotropic medium. The closed-form expressions derived for such a constitutive law allow for its implementation into a f.e.m-based numerical procedure. The computational code so obtained is then applied to simulating the response of a foundation soil reinforced by a group of floating columns, expressed in terms of load-settlement curves drawn up to the ultimate bearing capacity.
