This paper reports the results of model loading tests performed on shallow footings resting on a double-layered deposit of Ticino Sand, a natural silica sand, with geosynthetic inclusions as reinforcement. The sand deposit is reconstituted by raining, using a travel-ling sand spreader apparatus at purpose developed, in two layers having different relative densities to simulate natural deposits. The soil is pluviated into a steel caisson (1.60x2.50x1.70 m) with reinforced wall; different model foundations, and types and assemblies of geosynthetic reinforcement are installed within. Analyses of the results in terms of bearing capacity, settlement and failure mecha-nisms are reported.

Abstract
This paper reports the results of model loading tests performed on shallow footings resting on a double-layered deposit of Ticino Sand, a natural silica sand, with geosynthetic inclusions as reinforcement. The sand deposit is reconstituted by raining, using a travel-ling sand spreader apparatus at purpose developed, in two layers having different relative densities to simulate natural deposits. The soil is pluviated into a steel caisson (1.60x2.50x1.70 m) with reinforced wall; different model foundations, and types and assemblies of geosynthetic reinforcement are installed within. Analyses of the results in terms of bearing capacity, settlement and failure mecha-nisms are reported.
