ABSTRACT

This chapter presents the description, classification and engineering characteristics of glacial soils emphasising the relevance of standard tests, techniques used to enhance those tests to produce useful data and data on glacial soils. Glacial soils are deposited by ice or by water or in water creating, in some instances, a unique landform, which helps identify the possible soil type. However, in the case of glacial soils, the geological classification is of use to the engineer as it provides additional information when interpreting the behaviour of these soils. Glacial soils are natural soils that are unlikely to have little or no organic content. Since the descriptions of engineering soils are of samples taken from boreholes, it is likely that any bedding noted will be thin to thinly laminated; and discontinuities close to extremely close. Thus, the complete description based on field observations and samples covers the particle sizes, discontinuities and engineering behaviour.
