Abstract

The purpose of this paper is to analyze the time-dependent behavior of subsoil under a reinforced embankment. An elasto-viscoplastic model EVP-MCC coupled with consolidation theory was used for the subsoil behaviour. The soil parameters were identified from laboratory tests and by inverse analysis from the settlements of the first four phases of the embankment loading. A FEM calculation was performed in order to obtain vertical and horizontal deformations and excess-pore pressure during the construction phases. A special attention was given to the effect of the reinforcement on the delayed deformations and on the stability of the embankment and foundation. The comparison between calculations and measurements demonstrated that the analysis by fully coupled EVP-MCC model and Biot's consolidation theory could adequately describe the time-dependent behavior of subsoil under a reinforced embankment.
