2D effect of static or rolling load on a granular platform above a soft soil reinforced by rigid inclusions
Résumé
The effect of static or rolling loads on a thin load transfer platform installed on a soft soil reinforced by rigid inclusions is investigated in a 2D geometry. The centrifuge model, scaled at 1/10th, consists of a sandy layer, an analog polystyrene soft soil and spaced vertical metal plates. A strongbox with a transparent face allows image analysis during loading. At a g-level of 10, this model was subjected to static vertical loading of a shallow foundation, and to mobile loading. Few round-trip cycles were carried out to simulate linear traffic. The roller mass can vary from test to test over the range of platform service loads up to the critical load measured statically.
