Abstract:
The evaluation of shear wave velocity in soil is so much desirable in geotechnical engineering due to its application to estimate the soil moduli under small strain condition. Obtaining the best travel-time is a main concern in calculating shear wave velocity in laboratory tests. Correct travel-time might be maskedby some unwanted phenomena such as near-effect. In present paper, basic parameters and specific application of different methods to examine shear wave travel-time i.e. temporal and mathematical methods are explained and their exactitude are comprised. Based on authors’ laboratory tests on granularsoils, maximum difference between different temporal method results is reached up to 0.09 ms. Crosscorrelation presents its best results when the first peak of the received signal is the greatest between all next peaks.
