Abstract

Pile installation by applying an impact to the top of a pile appears to be a simple construction process but analysis of that process is complicated as it involves a source of energy, the structural member (pile), and the ground into which the pile is driven. Codes and regulatory standards suggest some basic guidance to analysis but much is still unknown. It is customary to monitor surface ground motions starting as close as 1.5 m from the pile and use the surface vibration data to interpret energy propagation. In this study, triaxial component geophones were placed on the ground surface during impact pile driving to monitor ground motion. Traditionally, researchers have assumed that the surface waves propagating from a vertical impact driven pile were Rayleigh waves and consequently, the vertical component of motion was only measured. The surface ground motion measurements obtained from this work revealed that the surface waves are not the classical Rayleigh waves that researchers have assumed so far.
