Abstract

To obtain a shear-wave velocity profile in geotechnical practice, various seismic investigation methods are being frequently used. In this paper, new site characterization method using harmonic wavelet analysis of wave (HWAW) method which is based on time frequency analysis was proposed. Field testing of this method is non-intrusive, and relatively simple and fast, and uses the signal portion of the maximum local signal/noise ratio to evaluate the phase velocity to minimize the effects of noise, and uses single array inversion which considers receiver locations. In order to estimate the applicability of HWAW method, field tests were performed at 2 sites. One is for evaluating accuracy of test method and the other is for estimating the applicability of 2-D imaging by HWAW method. Through field applications and comparison with other test results, the good accuracy and applicability of the proposed method were verified.
