Retaining wall with reinforced backfill – a case study

Abstract The paper deals with the design, construction and cost economics of a 11 m high and 19.50 m long random rubble stone masonry wall retaining reinforced earthfill. The cohesionless earthfill, available at the site of construction, was reinforced by geogrids that were not attached to the wall backface. The new design philosophy, developed for designing rigid walls with reinforced cohesionless backfill, has been discussed in brief but has been explained in detail for a 11 m high wall. The wall was built on a national highway in the lower Himalaya in September 1991.
