Kurzbeschreibung This groundbreaking book is the first to introduce the fundamental governing principles of unsaturated soil mechanics. Focus is given to principles rather than specific applications, making this unique volume more broadly applicable and adaptable. Its easy-to-follow approach is based on the mechanisms for soil suction and suction induced stress; the relation between soil suction and effective stress; and soil strength and deformation.
