Abstract
Since the introduction of the SASW method the use of surface waves for soil characterization has gained great popularity in geotechnical engineering. The typical two-receiver testing configuration shows some inherent drawbacks, for this reason a multistation approach is proposed in this paper. The dispersion curve evaluation with a multistation scheme has several advantages. First of all, the estimate is much more stable and less sensitive to noise and internal phases of the instruments. Moreover signal interpretation is much clearer with respect to SASW approach and there is no need for subjective choices in the construction of the experimental dispersion curve. For this reason the procedure is easily automated, with a great saving of time and the possibility of having a rapid estimate directly on site. Some experimental results are presented to compare the multistation fk analysis of surface waves with the classical two-station procedure of SASW tests. The experimental dispersion curve is finally used for an inversion process based on the simulation of wave propagation in a layered elastic medium. The obtained shear wave profile is then compared with the results of a Cross Hole test.
