Abstract

Matrix of wave propagator across cracks inside piles is introduced, and applied to the frequency responses of piles with defects such as crack, hollow or swell segment. Numerical analysis is in agreement with experimental results. This theory presents a sound basis for the evaluation of the integrality of piles by impedance method and other dynamic testing technique based on the analysis of frequency response of piles.
