Abstract
Displacement piles are driven to support a wide rangeof structures. Predicting their axial limiting capacities and load-displacement behavior is critical to many such engineering applications. While field load tests may be conducted to check design assumptions, such tests can prove expensive and difficult to generalize. Numerical analyses undertaken to support design face uncertaintyover the potentially important effects of pile installationasno well-developed method exists to predict the stresses applying during and after driving. Recent experiments have provided evidence regarding the stresses and strains developed around displacement piles during installation in sandthat can help guiderepresentative numerical modeling. This paper contributes to this development by reporting large displacement numerical analysesand linking these to high-quality experiments. The Arbitrary Lagrangian-Eulerian (ALE) options available in ABAQUS/Explicit have been employed to simulate highly instrumented calibration chamber tests made with closed-ended pilespenetrated into sand. Predictions for the stress components developed during and afterpile installation are presented, along with measurements made by other authors of the corresponding strain fields. The simulations’ broad agreement with the available experimental evidenceindicatesthat the adopted ALE techniqueand soil modeling approach are appropriate for pile installation analysis in sands.
