Effect of the installation methods of piles in cohesionless soil on their axial capacity
Résumé
An experimental campaign has been realized to study the effect of the installation method on the axial capacity of piles. Different installation methods have been used to jack the tested piles at 1×g and 100×g in dense Fontainebleau sand. The results of the compression and tension tests carried out on these piles show important impacts of the installation method on their axial capacities. The pile total compression capacity, as well as shaft and tip resistance are analysed. Pile total tension capacities are also studied. A significant increase in the tension capacity is observed in cyclically-jacked piles unlike piles monotonically jacked at 100×g.
