| Abstract: | In this paper the wave theory is applied to study the propagation and reflection of the transient waves excited by hitting the top of piles,to explain the constitution of the response on the top and to derive the expressions of the amplitude and phase spectrums. Attention is given to the dissipation and dispersion of wave signal in pile-soil system, and a detailed discussion is devoted to the influence of these phenomina on the peak values and peak frequencies of the amplitude spectrum. So an adequate basis for evaluating the integrity of piles is provided. |
