ABSTRACT: An experimental laboratory investigation on spatial deformation beneath reinforced and unreinforced embankments using nonintrusive method was performed. Transparent clay was used to model the clay foundation soil. The transparent artificial clay was made from amorphous silica powder with the same refractive index as pore fluid. Deformation measurements were made using laser source, a line-generating lens and a digital camera capturing images of deformations through a Plexiglas tank. The two-dimensional spatial deformation patterns were obtained by correlating consecutive images using Particle Image Velocimetry (PIV). The results of laboratory investigation are discussed in this paper.

RÉSUMÉ: Une investigation expérimentale sur les déformations spatiales en dessous des digues renforcées par des géocellules et des digues non- partage le même indice de réfraction que le fluide interstitiel. Une échelle de déformation a été faite en utilisant une source laser et une lentille qui produit des vecteurs et un appareil photo numérique qui capture des images des déformations à travers
