AbstractLeda clay is a highly sensitive material located in one of the most industrialized regions in Canada. Its behaviour related to engineering problems and solutions is reviewed. Among the many characteristics of this clay, two stand out: 1) the existence of a clay structure formed as a result of deposition environment, age and geologic history, and 2) time dependent behaviour of the clay under external loading. These characteristics influence the magnitude and rate of settlement under embankment, stability of embankments, natural slopes and cuts, pile design, dynamic safety of earth-structures, settlement due to shrinkage and freezing problems. Based on testing in the laboratories as well as in the field and case history studies over the past three decades, geotechnical engineers now have developed acceptable solutions to each of these engineering applications. They are discussed in this paper.
