Challenges in numerical modelling of screw piles installation and vertical loading based on centrifuge testing
Challenges in numerical modelling of screw piles installation and vertical loading based on centrifuge testing
Recent advancements in physical modeling have enabled a realistic representation of construction stages and installation procedures for complex geostructures. For instance, the process of precast pile installation, such as screw piles with great potential in offshore engineering, has been persuasively replicated in centrifuge testing, allowing for the measurement of associated forces and displacements. On the other hand, numerical modeling has become a widely accepted approach for assessing soil-structure interactions, serving design purposes, or generating digital twins while numerical simulation of physical testing entails considerable challenges. Considering the geometrical details and the complex load transfer mechanism associated with screw pile installation, this paper discusses the challenges involved in the modelling of pile installation process from the in-flight CPT test to the simulation subsequent vertical loading, taking scaling aspects into account. As a result of this research, the paper will present appropriate strategies for simulating screw pile foundations with 3D complex geometries based on observations from physical tests.
