Glacial soils are composite soils with significant variations in composition and properties and are recognised as challenging soils to deal with - and they do not always conform to classic theories of soil mechanics.
This book for designers and contractors brings together many years of experience of research in both earth scienc

Testo aggiuntivo
"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
