ABSTRACT: Using native soils as the reinforced fill material in Mechanically Stabilized Earth (MSE) structures can be problematic especially if the native soils contain a large percentage of fines (d<0.075mm) and are poorly graded. Several case histories of TerraSteep retaining walls, a welded-wire-form faced MSE structure using such native soils in the Greater Toronto Area (GTA) have been reviewed and discussed in this paper with respect to their design, construction and performance during and after installation of the walls based on monitoring data.

RÉSUMÉ: remplissage renforcé dans des structures en terre stabiliséee mécaniquement (MSE) pourrait être problématique si les sols naturels contiennent un grand pourcentage de fines de la conception, de la construction et de la performance pendant et après l'installation de plusieurs murs de soutènement du type «TerraSteep» utilisant les sols indigènes de la région de Toronto.
