AB - This paper investigates the axial load capacity of a pre-loaded pile installed in soft clay and subjected to vertical loading. Previous studies on pre-loaded shallow footings have shown that the undrained shear strength of soft clays is enhanced with time due to the dissipation of the excess pore water pressures generated during initial loading, as well as due to the soil ageing, after all pore pressures have dissipated, associated with creep. It remains a question whether the pile load capacity is enhanced with time as well, after the effects of installation have settled. The problem is investigated by means of a series of coupled finite element analyses, thus taking account of consolidation processes in the ground, in which the soil is modelled using an elastic-plastic constitutive model. Subsequently a similar set of coupled analyses is performed, using an elastic-viscoplastic model, to examine the effect of creep on pile capacity. © 2010 Taylor & Francis Group, London.
