Abstract
A method to estimate the shape of the foundation piles is described. The head of the pile is hit with a small hammer and the reflected wave is recorded with a vibration pick-up attached to the same head. The method automatically estimates the shape of the pile from the recorded wave. By computer simulations and experiments using model piles, it is confirmed that the proposed method correctly estimates the shape of the underground piles
