The principle, technology, structural design, practical procedure, and fields of application are described on reinforced earth masses particularly as related to retaining structures. Reinforced earth is a composite material formed by the association of soil and reinforcement in the form of metal strips placed horizontally, and which are capable of withstanding large tension forces. The length of reinforcing strips and their density (cross section and spacing) are determined by calculations for the internal stability of the reinforcing earth structure. Facing elements (metal or precast concrete) retain the soil between the layers of reinforcements in the immediate vicinity of the wall facing. The service life of reinforced earth structures depends on the resistance of the reinforcing strip to corrosion. The selection of the soil for a reinforced earth structure is based on technical as well as economic considerations. The composition of reinforced concrete backfill, and the design of reinforced earth structures are outlined, as well as their construction control and supervision.
