DESIGN ASPECTS OF REINFORCED EARTH CONSTRUCTION

This article discusses how a reinforced earth wall fits in with other components of a road cross-section--the road pavement, drainage, services, safety fences, and parapets. An example of a reinforced earth wall supporting a motorway embankment is considered. The cost of a typical 6 m high wall is made up as follows: Selected fill--30%, reinforcing elements--30%, connections--5%, cladding units--35%. Most of the reinforced earth retaining walls that have been built throughout the world have used metallic strip reinforcing elements. An example of the typical properties of four metallic reinforcing elements are presented. Also included is a comparison of the percentage extension at working load, the relative cost of supply per unit force, and the relative weight per unit force for these four materials. It is noted that one of the advantages of metallic reinforcing elements is the ease with which they can be connected to the cladding units. One problem designers have is in deciding what properties to assume for the fill in and behind the wall. It has been shown than an equivalent cohesionless fill with an angle of internal friction of 30 degrees and density equal to 19K N/M cubed would give a conservative prediction of earth pressures for most fills used in this country provided the wall is not greater than 12 m high.
