D-Pile Group – Plasti-Poulos


As an extension of the Poulos model the Plasti-Poulos model includes non linear single pile behaviour based on the analysis of a pile in multilayered non linear soil. The behaviour of the half space is similar to the Poulos model (elastic). The Plasti-Poulos model can therefore be used for more accurate analyses compared to the Poulos model, in particular when larger loads are imposed and the system starts to show non linear effects.

  • Elasto-plastic soil behaviour.
  • Layered soil (max. 99 layers).
  • Pile-soil-pile interaction for 2 layers.

D-Pile Group comes as a standard module, which can be extended further with other modules to fit more advanced applications
