Özet

Prediction of the ground shaking response at soil sites requires knowledge of the soil, expressed in terms of shear wave velocity. Although it is preferable to measure this dynamic soil parameter in situ, this is often not economic at all locations. Existing correlations between shear wave velocity and penetration resistance have been assessed in this study and compared with correlations with SPT values obtained based on geotechnical and geoseismic data collected from a first-degree earthquake zone in Turkey. The results obtained support the findings of earlier studies that blow-count is a significant parameter in these correlations while type of soil has no important influence. The regression equations developed in this study compare well with most of the previous equations and exhibit good prediction performance. It is noted that better correlations are obtained when uncorrected blow-counts are used.
