Abstract
  • The concept of placing high strength linear reinforcements in a soil backfill to produce a vertical retaining structure is a recent idea that has been applied with success at a number of locations. Rational procedures have been developed for the design of these structures when the reinforcements consist of long metal straps. In certain situations advantages in construction and economy could be gained by replacing the metal straps with a continuous high strength fabric as reinforcement. The purpose of this investigation was to examine the behavior of a number of fabric reinforced earth models and to determine if the design methods that have been applied to metal strap reinforced earth walls can be applied to fabric reinforced walls. The economic feasibility of fabric reinforced earth walls was also investigated. The results of the model tests indicated that the design of fabric reinforced earth walls using methods developed for metal strap reinforced walls produces conservative results. Further investigation is required to define the actual mechanism involved in fabric reinforced earth walls. The economic analysis indicated that fabric reinforced walls can be competitive with other types of retaining structures for low heights.
