REINFORCED EARTH

REINFORCED EARTH, AS A NEW MATERIAL, CONSISTS OF AN ASSOCIATION OF EARTH AND REINFORCEMENTS, THE LATTER BEING LINEAR ELEMENTS ABLE TO WITHSTAND IMPORTANT TRACTION FORCES. A THEORY, BASED ON SIMPLIFIED ASSUMPTIONS, HAS BEEN WORKED OUT FOR THE INTERNAL STABILITY DESIGN OF RETAINING WALLS. LABORATORY STUDIES ON BIDIMENSIONAL MODELS ARE MADE WHERE THE EARTH IS SIMULATED BY A CYLINDER PILING AND THE REINFORCEMENTS ARE MADE OF ALUMINUM BANDS OF VERY SMALL THICKNESS. THE ADVANTAGES OF THE MODEL TESTS ARE THAT THEY ARE SIMPLE, QUICK, AND CHEAP. HOWEVER, THEY DO NOT PERMIT MEASUREMENTS OF THE STRESSES WITHIN THE EARTH OR TRACTION FORCES WITHIN THE REINFORCEMENTS TO BE MADE. EXPERIMENTS ON ACTUAL STRUCTURES ARE NEEDED. AN IMPORTANT POINT IS THE CHOICE OF THE EARTH TO BE USED. PURELY GRANULAR SOILS ARE THE IDEAL MATERIALS; A FEW CRITERIA ARE SUGGESTED BASED ON THE GRAIN SIZE AND THE UNDRAINED SHEAR STRENGTH. STABILITY OF THE FOUNDATION AND SETTLEMENTS, DRAINAGE, AND CONSTRUCTION ARE OTHER PROBLEMS TO BE CONSIDERED.
