Investigation on Behaviour of Open-Ended Driven Piles in Different Cohesionless Soils Using Image-Based Measurements
Driven piles are the most common types of deep foundation elements installed using impact or vibration hammers to a desired depth of resistance. Hollow driven piles are always preferred since it is suitable for all ground conditions and can be installed at a faster rate with minimal ground disturbances. This paper discusses the prospective of using Geo-PIV image-based technique to investigate the pile soil interaction behaviour in different soil deposits. The plane strain experimental studies are carried out in a steel tank of dimensions 600 mm × 200 mm in plan and 450 mm depth. Half-section hollow aluminium piles modelled using wood’s scaling law are used in the experiments. Three different infill mediums such as cohesionless sand, quarry dust and crushed stones at different densities are used, and impact load has been applied to drive the piles. The deformation behaviour at interface region is captured using a high-resolution digital camera that is later analysed through Geo-PIV software. From strain contours obtained through image analysis, it is observed that for piles driven in crushed stones, shear flow of grains around piles is highest, whereas it is lowest for piles driven in sand deposits.
