ABSTRACT: The use of deep soil mixing technologies has become increasingly common in North America following its widespread development and adoption in Asia and Scandinavia. This research project considered how design of a stabilized soil mass can be optimized for a land reclamation project that satisfies both stability and serviceability requirements. The purpose of this work was to study the impact of the use of reclaimed clay in sandwich construction on global stability and settlements. These findings may be used for the economic design of future land reclamation projects requiring deep soil mixing and site grading construction using excavated soft soils in combination with imported granular fill. Limit equilibrium slope stability analysis combined with one dimensional consolidation analysis were used to satisfy commonly used stability and settlement criteria.

RÉSUMÉ: de sol en profondeur est devenue de plus en plus commune en Amérique du la conception d'une masse de sol stabilisée pour un projet de redirectrices pour une conception économique des projets futurs de remise en état des terres en utilisant un mélange de sol en profondeur et son nivellement à partir de sols meubles excavées combinés avec du remblai granulaire importé. Une analyse de stabilité de pente limite combinée à une analyse unidimensionnelle de consolidation ont été utilisés pour satisfaire aux critères de stabilité et de tassement couramment utilisés.
