ABSTRACT: The shear wave velocity, Vs, is a fundamental parameter allowing characterization of a soil in elastic domain ( < 10-3). A certain number of equations are found in the literature to estimate Vs based on other geotechnical parameters. This paper presents the range of Vs values based on published equations for five saturated deposits of the Champlain Sea clay. However, the range of Vs values calculated shows an important scatter and raises questions about the applicability and accuracy of the existing correlations. This analysis emphasizes the need for a greater accuracy in Vs estimates from equations relating this parameter with routine geotechnical properties in order to use this parameter for geotechnical characterization purposes. As such, it is required to develop more precise laboratory Vs measurement tests. Results reported herein appear to justify the efforts undertaken jointly by the University of Sherbrooke and the École de technologie supérieure towards these goals.

RÉSUMÉ: La vitesse de propagation des ondes de cisaillement, Vs est un paramètre fondamental permettant de caractériser un sol dans le domaine élastique. Des publications ont présenté des équations permettant de relier Vs paramètres géotechniques. Cet article présente des Vs calculées à partir de corrélations tirées de la littérature pour cinq dépôts argile de la mer de Champlain. Mais les valeurs obtenues soulèvent la précision des corrélations utilisées. Cette analyse de disposer de corrélations plus précises entre les propriétés géotechniques usuelles et Vs afin que ce paramètre puisse être utilisé pour fins de caractérisation géotechnique. Il appert que des essais plus précis de détermination de Vs en laboratoire doivent être mis au point. Les résultats rapportés ici paraissent justifier les efforts en ce s
