Aktuelle Richtlinien berücksichtigen die Pfahl-Boden-Interaktion nicht ausreichend so dass nur ein vollständig numerischer GMNIA-Nachweis geführt werden kann. Für derartige Berechnungsmodelle fehlen allerdings derzeit noch validierungswerte für eingebettete Schalen. Experimente im Rahmen des VERBATIM-Projekts schließen diese Lücke.

We discuss about methodologies for utilizing site-specific geotechnical (CPT) and geological data, aiming to construct an integrated ground model that can predict stratigraphic profiles and useful for geotechnical design parameters at any location within a 3D domain. The predicted parameters and stratigraphy are then used to predict the probability of potential pile tip damage, upon collision with a boulder.
