Reinforced earth is the method of mobilising the friction developed between soil particles and reinforcing strips placed at stipulated intervals, horizontally and vertically, to create an “earth-retaining structure”. The concept and analysis of reinforced earth is as far removed from anchored or conventional earth-retaining structures as prestressed concrete was from reinforced concrete. Until this has been accepted, it is impossible to appreciate fully the analysis and advantages of this new technique.
