Abstract: An object of the present invention is to provide a system and a method for evaluating an urban ground stability using traffic noise, which derive a physical property (S wave velocity) according to a depth by performing an inversion for a surface wave dispersion curve generated by traffic vibration in order to more accurately derive an underground physical property value (S wave velocity).
In order to achieve the object, a system for evaluating an urban ground stability using traffic noise according to the present invention includes: a signal measurement unit measuring a passive elastic wave signal generated by the traffic noise, and acquiring an elastic wave signal containing refracted waves using an artificial transmission source in an exploration area; and a server performing an inversion by applying a surface wave dispersion curve inversion technique to a frequency-phase velocity dispersion curve according to the passive elastic wave signal or the elastic wave signal containing the refracted wave.
