Abstract

In this paper a simplified procedure to incorporate some installations effects into the numerical finite element modelling of screw pile uplift is presented. The procedure consists of the approximation of the installation phase through 1) the application of a compression loading corresponding to successive embedment depths, 2) the use of modified soil properties over a disturbed zone. Pre-defined failure mechanisms are added to introduce some weakened zones due to either soil disturbance or strain-localisation. The results of numerical simulations are compared to a centrifuge test undertaken at the University of Dundee. The simulation considering an inclined failure mechanism and the simulated installation better captures the uplift capacity and initial stiffness.
