Abstract

The term “Reinforced Earth” or “Reinforced Soil” is used to describe a Soil mass reinforced with tension resistant element. Reinforced Earth is primarily a composite material, conceived by the French Engineer Henary Vidal in 1966. It is combination of Soil, generally cohesion less and the tension resistant element in the form of strips, sheets, synthetic fabrics or fibre reinforced plastics. The reinforcement is so arranged in the Soil mass as to reduce or suppress the tensile strains which might develop under gravity forces. The Soil is held in position by the frictional force developed between the Soil particle and the reinforcement. The Soil mass in between two successive reinforcement layers are assumed to be held in position by arch action. Reinforced Earth has found great use in construction of retaining structures. Reinforced Earth walls are generally economical when the sub Soil conditions are poor. Its construction is very rapid and is able to withstand considerable settlements. The present study is mainly based to investigate the increased retaining capacity of retaining walls without any increase in the thickness of the wall element with increased height compared to retaining earth without reinforcement. The study aims at verification and establishment of the concept of increased retaining capacity of retaining walls with increased height and slender sections with limited experiment using Damodar sand and steel strips reinforcements. The results of the experiment have established the postulate. Its purpose is to illustrate procedures to arrive at reinforced earth construction. In this work a tremendous increment in retaining capacity of reinforced earth retaining wall is observed.
