Abstract:Damage to structures due to vibrations from pile driving operations is of great concern to engineers. This
research has stemmed from the need to address potential damage to concrete-filled pipe piles and recently
placed concrete structures that could be affected by pile driving vibrations. The study will focus on two topics:
(1) The attenuation of potentially damaging pile driving vibrations with distance from the source, and (2) The
effects of distance and curing time of concrete on the quality (unconfined compressive strength) of recentlyplaced
concrete exposed to pile driving vibrations. The effects of pile driving vibrations did not cause problems
with concrete compressive strength except for the case where concrete had only cured for 4 to 6 hours before
vibration.
