Unsaturated Soil Mechanics in Geotechnical Practice

"Soil will, either seasonally or occasionally, pass from the unsaturated to the saturated state and even from unsaturation to dryness. The theory of unsaturated soils is dealt with, including its application to natural undisturbed soils and compacted soils. Application of the theory to soil-like materials such as mine waste and municipal solid waste is also covered. Application of the theory to practice is illustrated by a number of detailed case histories. Unsaturated soil mechanics principles can also successfully and usefully be applied in related fields such as the bulk storage of particulate materials, underground mine support, solution mining and concrete structures"--

Geoffrey Blight completed his Bachelor and Master degrees at the University of the Witwatersrand, Johannesburg, and his PhD at Imperial College, London. There he carried out some of the earliest research on the mechanics of unsaturated soils, under the supervision of the legendary Alan Bishop. His early work, published jointly with Bishop and others in 1960, 1961 and 1963, provided data that is still being used by new generations of researchers on unsaturated soil behaviour. He soon became interested in the application of unsaturated soil mechanics to residual soils and mine waste and has published extensively in these areas. He has also applied unsaturated soil mechanics principles in related fields such as concrete and silo technology. He was a member of the International Society for Soil Mechanics and Foundation Engineering’s Technical Committee on the Properties of Tropical and Residual Soils from 1982 to 1997 and served as Chairman from 1994 to 1997. He edited and co-authored the first (1997) edition of "Mechanics of residual soils", which was produced during his Chairmanship. In addition to the second edition of Mechanics of residual soils (2012), he has also authored or co-authored the books: "Assessing loads on silos and other bulk storage structures" (2006), "Geotechnical engineering for mine waste storage facilities" (2010), "Alkali-aggregate reaction and structural damage to concrete" (2011), all published by CRC Press/Balkema.
