The Analysis Of Piles

Abstract
The application of a contact-friction algorithm for modeling the pile-soil
interface in the analysis of pile foundations is presented. The algorithm is
based on the penalty method and uses a "slideline" formulation. This model
permits large relative sliding with friction. The adhesion between pile and
soil, which is dependent on the effective stress in the soil surrounding the
pile, is simulated using an equivalent total-stress approach. The contact
algorithm is incorporated into a nonlinear dynamic axisymmetric finite-
element model and is applied in the driving and axial capacity analyses
of a prebored concrete pile in undrained clays. The cases of normally-
consolidated and overconsolidated clays are co
