A New Earth Reinforcement Method Using Soilbags
- This format is currently out of stock.
Soilbags are usually incorporated into temporary structures, rather than being used in conventional construction, as they have a tendency to deteriorate rapidly on prolonged exposure to sunlight. The amazing bearing capacity of soilbags has, however, inspired the development of an earth reinforcement method in which the bearing capacity of soft foundations is enhanced, reaching ten per cent of that of concrete. New methods have seen their projected durability as a semi-permanent material extend to in excess of fifty years, provided that direct exposure to sunlight and ultra-violet rays is avoided.
This book covers the development, properties and characteristics of soilbags, as well as design features of structures built by this method. The geotechnical applications in, for example, railway ballast foundation reinforcement, retaining walls and embankment constructions are extensively described and richly illustrated by reference to case studies from Japan. The intention is to stimulate a wider, international adoption of the method in earth reinforcement and civil engineering construction, with particular reference to developing countries. Geotechnical and foundation engineers and other professionals working on earth reinforcement will find this a valuable work, while it will provide supplementary information to graduate students in soil mechanics and foundation engineering.
