Abstract

A series of pile jacking and driving tests in a plane strain calibration chamber is presented in this paper. The calibration chamber was made of transparent acrylic that allows visualization of the pile installation process. High resolution images were taken while the pile was jacked into confined granular media. Parallel tests were performed in which a drop weight was employed to drive the pile into place. The two installation methods were compared in terms of soil response in the near field. Digital Image Correlation (DIC, aka. PIV) was employed to construct the incremental displacement field during penetration. Test results were used to gain insight into the nature and magnitude of spatial distribution of displacements in the vicinity of a pile as a result of jacking and driving. Evaluation of the displacement fields revealed that jacking results in lower lateral displacements compared to driving.
