2D behavior of a granular platform above a soft soil reinforced by rigid inclusions and geogrid subjected to a rolling load traffic

Résumé

In a 2D geometry, the effect of rolling loads on a thin granular platform based on a soil reinforced by rigid inclusions, is studied on centrifuged model. Scaled at 1/10th, the physical model consists of a sand Fontainebleau NE34 layer, an analog polystyrene soft soil and spaced vertical metal plates. A strongbox with a transparent face allows image analysis. At a g-level of 10, fatigue tests on a few round-trip cycles were carried out to simulate linear traffic. Perturbations in arching effects in the platform are observed, even with a geogrid reinforcement.
