Abstract

The present work investigates the influence of installation technology on the response of a single pile under axial load. Installation and loading process for both jacked and screw piles has been analysed through a Discrete Element Model (DEM) approach, by means of the commercial software Particle Flow Code 3D v3.0 (Itasca). The Thesis is subdivided in two main parts. Firstly, CPTs tests in calibration chamber available in literature have been used as the starting point for the analysis of full scale CPT and the installation jacked pile. Issues deriving from the use of DEM for simulating the problem at hand are thereby discussed, elucidating the role played by key dimensionless geometrical parameters affecting the numerical simulation. In the second part, installation as long as loading process of a closed-ended jacked pile and the Full Displacement Pile (patented by BAUER Maschinen Group S.p.A.) in sands with different initial properties have been analysed. The role played by different parameters on pile response is discussed in light of the established knowledge in the subject.
