| Abstract | Leda clay is an extremely sensitive post-glacial marine clay occurring in the St Lawrence and Ottawa valleys. This paper summarizes some geotechnical data which have been obtained during foundation investigations near the city of Ottawa. The geological history of the deposit is described and preliminary test results on mineralogical composition of the material are presented. Generally the natural water content of the clay is higher than the liquid limit. Sensitivities range from extra-sensitive to quick. Due to the sensitivity, sampling must be carried out carefully. Test results on several borings are presented graphicaly showing variation of water content, Atterberg limits, shear strength and preconsolidation load with depth. Some data on sensitivity, salt concentration and grain size are also presented. The significance of the variation in these properties is discussed. |
