The purpose of this paper is to present guidelines and correlations to assists geotechnical engineers in estimating Vs profiles in Norwegian clays in the absence of site-specific data. For this, a database of in situ Vs measurements and standard geotechnical engineering material properties for Norwegian clays has been established. The database allowed the development of several empirical correlations between in situ Vs and basic soil properties, cone penetration parameters, undrained shear strength and 1D compression parameters. Based on the results from regression analyses, empirical functions based on cone penetrometer data to determine the best estimate in situ Vs of Norwegian clay are recommended to use when in situ measurements of Vs at the site are not available. Relationships based on undrained shear strength can also be used in practice as presented herein.
