Geotechnical Properties of Glacial Lake Clays

This article reports on a study of the properties of glacial lake clays. Data collected from a number of sites in the Great Lakes area of the United States are presented. Despite local variations in subsoil conditions and the large distances between the sites, the clay deposits investigated have much in common and it is possible to study them as a related family. An analysis was made of the principal factors that control the strength characteristics of the clays. The shearing resistance and sensitivity were found to be intimately related to the structure of the clay as well as the stress history.
