Résumé

A numerical model developed using the finite element Plaxis program is presented in this paper to
simulate the behaviour of a stiff “L” shaped retaining wall supporting sand. For validating the
proposed numerical model, reference was made to an experimental model tested in a centrifuge
experiment. The proposed numerical model intended to predict the behaviour of a target prototype
and to check the validity of the modelling concept used. Taking into account the geometry and
dimensions of the wall with respect to the centrifuge scaling law, the loading conditions and
considering the hardening soil model, it was found that the predicted pattern and magnitude of the
wall displacements were close to the experimentally observed results. A good agreement between the
measured and the numerically computed lateral pressures acting on the wall stem was also obtained
with comparison to the classical approach.
