ABSTRACT: Thirty-five years ago seismic sensors were added to the piezocone probe to create the seismic cone penetration test (SCPTu). The CPTu test is a well established tool for geotechnical soil characterization. By adding shear and compression wave velocity measurements, SCPTu results can be used to characterize small-strain stiffness, cementation, density, compressibility, age, and susceptibility to cyclic liquefaction. We have reviewed the development of the seismic sources, seismic cone modules, test procedures, and interpretation of the SCPTu. We have complemented published literature with new data traces to demonstrate findings. We conclude with suggested areas for future research.

RÉSUMÉ: Il y a trente-cinq ans les capteurs sismiques ont été ajoutés aux piézocônes pour créer les piézocônes sismiques (SCPTu). et la rigidité de petites déformations. Nous avons passé en revue le développement des sources sismiques, des modules de piézocône sismique, des modes opératoires ainsi que des interprétations du SCPTu. Nous avons complété la documentation publiée avec des traces de données nouvelles pour démontrer les résultats. Nous concluons avec des zones proposées pour de futures recherches.
