Zur numerischen Modellierung von Vollverdrängungsbohrpfählen

Numerical modeling of full displacement piles

The installation process of full displacement piles is simulated numerically using a three dimensional model. The coupled Eulerian-Lagrangian method is applied, that makes the simulation of geotechnical problems with large deformations possible. The crowd force and the torque are carried out during the simulation to investigate the influences of the installation technique and the geometry of the drilling tool. The rotational speed is varied at constant penetration velocity. The influences on the soil surrounding the pile are determined investigating the stress changes in this area.
