Abstract

Increasing in vehicular demands a large number of flyovers, moreover there is tremendous increase in the number of highways, in hilly areas. Here earth retaining structures are essential. For many years, retaining structures were made of reinforced concrete and were designed as gravity or cantilever walls which are essentially rigid structures and cannot accommodate significant differential settlements unless founded on deep foundations. For solving this problem Mechanically Stabilized Earth Technique is used. It is a construction technique with alternate layers of compacted soil and reinforcing elements to build retaining walls and embankments. The reinforcing elements, which can be either steel or synthetic, interact with the soil by friction and confinement and provide tensile capacity. The combination of soil and reinforcement behaves as a gravity mass that retains lateral earth pressures. The two materials produce a composite structural material that combines their best characteristics. The structure, which is constructed by this technique i.e. Mechanically Stabilized Earth Wall, is much flexible and due to this it can accommodate large settlement. And 35% to 50% cost saving is done over RCC wall. In this paper, introduction of MSE wall, literature review, material and its properties, behaviour, construction techniques and steps, design concepts, design and then discussion for results of design, is includes. This paper addresses to evaluate and verify the performance of MSE wall in different condition of retained soil and backfill soil with different types of reinforcement with variable vertical spacing. Here how the reinforcing material and soil properties as well as vertical spacing between reinforcing element are affecting on stability of MSE wall is studied. Design of MSE wall is done as per BS 8006:1995 for out of water condition. Here design work is carried out for three different types of retained soil by adopting different backfill soil and reinforcing materials. In first case i.e. A, stability is checked for only one type of backfill soil. Where as in the second case i.e. B, two types of backfill soil and in third case i.e. C three types of backfill soil, are used to check the stability. In each case four types of reinforcing elements are used for four different vertical spacing.
