Abstract
Numerical simulations of the installation process of full displacement piles are presented. A Coupled Eulerian–Lagrangian approach is used to simulate the installation process. The influence of different ratios between the rotational and the penetration velocity are analyzed. A hypoplastic constitutive model is used to match the soils behavior realistically. The reaction forces of the drilling tool are determined. Furthermore, the influence of the surrounding soil is investigated. The displacements nearby the drilling tool are analyzed as well as changes of the stress state and the bulk density. The numerical results are used to explain the effects in the soil, that were observed during in situ measurements.
