A finite-difference based continuum numerical model is developedfor the pile-soil dynamic response
during pile driving. The model is capable ofsimulating the wave propagation analysis along the pile shaft and
through the soil media. The pile-soil media, loading and boundary conditions are such that axisymmetric
assumption seems to be an optimized choice to substantially reduce the analysis time and effort. The
hydrostatic effect oj water is also considered on the effective stresses throughout the soil media and at the pilesoil
interface. The developed model is used for signal matching analysis ofa well-documented driven pile. The
results showed very good agreement with field measurements. It is found that the effect of radiation damping
significantly changes the pile-soil stiffness due to the hammer blow. The pile rip response shows substantial
increase in soil stiffness below and around the pile tip due to driving efforts.
