AB  - 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.
