Effect of particle size distribution on pile tip resistance in calcareous sand in the geotechnical centrifuge

摘要

Until recently, the micro mechanical origins of soil behaviour have remained illusive, but it is now known that that the constitutive behaviour of a soil is largely determined by its particle size distribution. This paper examines the specific boundary problem associated with the penetration of a model pile into two different gradings of dry calcareous sand in a geotechnical centrifuge, in or- der to establish the effect of he inclusion of fine particles on the pile end bearing resistance.
