Effect of Horizontal Reinforcement on Stability of Earth Masses.
Abstract
Reinforced earth consists primarily of soil whose engineering properties and performance have been improved by the introduction of small quantities of frictional material that possesses a relatively high tensile strength and modulus of elasticity. The design concept of reinforced earth is based on the assumption that the induced lateral force of a restrained soil mass under load will be resisted by frictional forces that develop between the reinforcement and the surrounding soil. This practical concept has been applied to the problem of stabilizing slopes, retaining walls, pavements, and other applications as described in the literature review. The objectives of this study were: (a) to investigate the uncertainties concerning the stree-strain distribution and the interrelation between the reinforcement and the surrounding soil, and (b) to evaluate the performance of neoprene-coated nylon fabric (membrane) versus galvanized steel as reinforcing material within a cohesionless soil mass. These two objectives were directed toward the feasibility of using the concept of reinforced earth in Corps of Engineers projects.
