ABSTRACT

The paper presents the results of experimental studies with regard to the response of small scale model strip footings resting on the surface of wrap-around reinforced soil retaining walls constructed using locally available sand as backfill and geotextile as reinforcing elements. Number of reinforcing layers and footing size were varied to find their influence on the bearing capacity and load deformation (both vertical and lateral) characteristics of the walls. It is found that the ultimate bearing capacity of the footings and initial tangent modulus increases with increase in the number of reinforcing layers but the initial tangent modulus decreases with increase in footing size.

Keywords: Geotextile; reinforced soil wall; strip footing; warp-around facing.
