Description
Book SynopsisAt some time 30% of the worldâs land mass was covered by glaciers leaving substantial deposits of glacial soils under major conurbations in Europe, North and South America, New Zealand, Europe and Russia. For instance, 60% of the UK has been affected, leaving significant glacial deposits under major conurbations where two thirds of the population live.
Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with. Understanding the environment in which they were formed and how this affects their behaviour are critical because they do not always conform to classic theories of soil mechanics.
This book is aimed at designers and contractors working in the construction and extractive industries to help them mitigate construction hazards on, with or in glacial deposits. These soils increase risks to critical infrastructure which, in the UK includes the majority of the road and ra
Trade Review
"I know that this one is a book I shall acquire and use... it is a book that merits reading from cover to cover.
It was a delight to see a book on engineering that recognizes the important role of geological processes in forming soils, therefore explaining their properties and behavior."
-- Eddie Bromhead, retired professor and consulting engineer
"This authoritative and well referenced book contains a wealth of information about glaciation, glacial geology and the engineering aspects of construction on and in glacial deposits."
-- John Hudson, Imperial College, London and past president International Society of Rock Mechanics
