REINFORCED SOIL, A NEW CONSTRUCTION MATERIAL

REINFORCED SOIL CONSISTS OF SOIL AND RENFORCEMENTS. REINFORCEMENT IS SUPPOSED TO ACT BY FRICTION IN CONTACT WITH THE SOIL PARTICLES GIVING THE MATERIAL SOME COHESION, THE ANISOTROPY OF WHICH DEPENDS ON THE APPLIED FORCES AND THE DIRECTION OF THE RIENFORCEMENTS. IN THE CASE OF SAND, IF FRICTION BETWEEN SAND AND REINFORCEMENT OCCURS WITHOUT SLIDING ACTION AND IF ONE ASSUMES THAT THE PLASTIC DEFORMATION OF SAND TAKES PLACE AT A CONSTANT VOLUME, REINFORCED SOIL CAN BE CONSIDERED AS AN ELASTIC MATERIAL, ITS MODULUS OF ELASTICITY BEING DEPENDENT ON THE MODULUS OF ELASTICITY OF THE REINFORCEMENT AND ON THE COEFFICIENT OF ACTIVE PRESSURE OF THE SAND. THE MOST FREQUENT EXAMPLES OF REINFORCED SOIL CONSTRUCTION IS THE RETAINING WALL. IT IS COMPOSED OF REINFORCEMENTS PLACED HORIZONTALLY AND PERPENDICULARLY TO THE WALL SURFACE, AND OF A SKIN OR FACE, THE PURPOSE OF WHICH IS TO RETAIN THE SOIL PARTICLES NEAR THE WALL SURFACE. REINFORCED SOIL COULD BE USED IN MANY OTHER TYPES OF CONSTRUCTION: AIR-SHAFTS, BEAMS, ETC. ONE OF THE MAIN ADVANTAGES OF REINFORCED SOIL IS ITS ECONOMY COMPARED WITH STANDARD TYPES OF CONSTRUCTION. /L.C.P.C./R.R.L./
