Shear wave velocity ([Formula: see text]) is often used for the calculation of the shear modulus to combat sampling issues in clays and minimize the cost of laboratory testing. Several studies reported correlations between [Formula: see text] and direct and indirect measurements of the cone penetration test (CPT), yet those proposed for fine-grained formations are generally of a local nature. This study sets out to propose a global approach for the estimation of [Formula: see text] for these soils. Seven regressions were developed using a total of 632 CPT data measurements collected from 55 different sites in 12 countries. The correlations utilizing the tip resistance and depth statistically outperform those using other CPT data. A total of 165 CPT points—collected from the state of New Jersey, USA, and Mexico City, Mexico—were used for verification. It is instrumental to analyze CPT data before building global correlations for gauging applicability and understanding limitations. The adopted approach paves the way for more methodical and rigorous global regressions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
