Abstract
The use of deep soil mixing technologies has become increasingly common in North America following its widespread development and adoption in Japan and Scandinavia. This research project considered how design of mass stabilized soils and sandwich construction may be optimized to achieve efficient large scale land reclamation that satisfies both stability and serviceability requirements. In this work the effect of several parameters on the global factor of safety for a land reclamation project was determined. The parameters included the thickness of the soft soil layer, as well as the strength, width, and location of a stabilized soil zone. The second phase of this work studied how dredged/excavated soft soils may be re-used for reclamation or site re-grading. The purpose of this work was to provide guidelines for the economic design of future land reclamation projects using deep soil mixing methods.
