REINFORCED EARTH--PRACTICAL DESIGN CONSIDERATIONS

The choice of reinforced earth for any particular application is a balance between aesthetic, economic, and technical considerations. Once the initial decision has been made to prepare a reinforced earth design it is important to appreciate the cost profile of the various elements in a reinforced earth scheme in order that the designer may optimize the design to produce the most economic solution. Reinforced earth structures are designed in accordance with the principles of soil mechanics. The analysis of any structure is usually considered in two parts: Internal stability and overall stability. The former is concerned with the estimation of the number, size, strength, spacing and length of the reinforced elements needed to ensure stability of the whole structure, together with the pressures exerted on the facing. Overall stability is the same as a mass or conventional retaining structure and is checked for forward sliding at the base, bearing pressure failure beneath the toe, and slip circle failure of the whole mechanism. The construction of reinforced earth structures is simple and it has been shown that it is frequently easier to build curved rather than straight structures. At present, the choice of reinforceing element lies between steel, prestressed concrete, aluminum, plastic or glass fiber reinforced plastic. The main considerations with regard to the reinforcement used are durability and cost.
