Abstract:

It is difficult to identify the frequency dispersion curve of the Rayleigh wave when obstacles exist in the foundation. For this situation, displacement curves of half space foundation were calculated using the finite element method, and were transformed into the frequency dispersion curve of the Rayleigh wave. Then its characteristics were acquired when there were sewage pipes in the half space foundation. The results showed that the reflected wave was received in front of the obstacles but not behind it, and the location and space of sensors had great influence on the calculated result. The results could provide reference for the identification of dispersion curves and the layout of sensors.

Key words: Rayleigh wave, obstacles, frequency dispersion curve, finite element method
