Abstract

In this paper a new numerical modelling technique for simulating the installation and loading of screw piles is described. The method uses the discrete element method (DEM) and in a single model is able to assess the installation requirements as well as the ultimate tensile and compressive capacity. Numerical modelling of screw piles has traditionally been conducted using finite element analysis (FEA), in which piles are wished in place into a soil body consisting of a meshed continuum. Although this has provided many insights into the capacity of screw piles and the mechanisms that form when they are loaded, they do not usually consider the effects of installation on the behaviour of the soil. Using 3D DEM calibrated against element tests and geotechnical centrifuge tests, it is now possible to assess the local changes in density and stress caused during the installation process and what effects this has on the capacity of screw piles.
