ABSTRACT: Accurate characterization of soft, sensitive coastal soils can be very challenging. In the past 30 years, several empirical correlations have been established to compare in-situ test results with commonly used geotechnical parameters. Many of the most popular correlations used a very wide range of soil consistencies to develop by using a 'best fit' approach. Because of this, these correlations may not be very representative for the extreme ends of the soil consistency spectrum. This paper examines and compares two of the most common in-situ exploration methods, seismic piezocone (SCPTu) and dilatometer (DMT) characterize soft sediments (su <60 kPa) at two sites using the established correlations.

RÉSUMÉ: La caractérisation des sols sensibles et mous peut devenir très ambigüe. Durant les 30 dernières années, plusieurs corrélations empiriques ont été établies afin de comparer les résultats des essais in situ et les paramètres de consistance généralement utilisés en géotechnique. Plusieurs des relations les plus utilisées ont été développées en utilisant la technique d'ajustement de la courbe de tendance. De cette façon, les corrélations ne sont pas toujours très représentatives, particulièrement en ce qui concerne les valeurs limites de la corrélation. Cet article examine et compare comment deux méthodes de mesure in situ, les essais au piézocônes sismiques (SCPTu) et le dilatomètre, caractérisent les sédiments mous (su<60 kPa) sur deux sites en utilisant les corrélations pré-établies. 1 INTRODUCTION
