Mobile tray for simulation of 3D load transfer in pile-supported earth platforms
Résumé
A composite foundation made of reinforced soft soil surmounted with a load transfer platform displays mechanisms such as arching in this mattress. In order to study the parameters of the mattress, such as its density, its nature, its particle size distribution, its height and the influence of the distance between the vertical stiff inclusions, the soft soil is being replaced by a perforated tray, which moves vertically. A detailed description of the mobile tray device is presented, with some preliminary results from a sandy mattress.
