In the past two decades, the digital image correlation (DIC) technique has been extensively used to evaluate the displacements and strains of soil medium in experimental geotechnics. For this, a sequence of photos is taken through a camera and is processed using a computer algorithm to evaluate the strains and displacements on the two-dimensional surface of the soil in an experimental study. The present investigation aims to assess the ability of evaluating the measurements using the DIC technique for two distinct geotechnical engineering problems i.e., slope failure and extraction of an under-reamed pile. In the investigation, 1-g physical model testing and Narmada river sand as soil medium are used. The failure planes are evaluated representing the failed slope and extraction of an under-reamed pile. Based on the outcome of the study, the efficacy of the DIC is assessed for two geotechnical engineering problems.
