Reinforced earth — Practical construction techniques : Ground Engng, V11, N7, Oct 1978, P24–26, 37

Abstract

The author illustrates the three methods of constructing reinforced earth structures: the concertina, telescope and sliding (York) methods. Examples are given of their use and their relative merits are discussed. In Britain a derivation of the concertina method is only used for temporary site works, although it is proposed to construct walls in Yorkshire with an acceptable appearance using fabric reinforcement. Details are given of the operational sequence and factors of importance in the York method of construction using lightweight material. Differences in the constructional sequence when a structural facing is used are discussed. Details are also given of base, drainage and capping methods. The ease of maintenance should be considered during the design stage including the replacement of hexagon facing units and top drainage. The author suggests that the design theories for the loads applied to the facing by the fill may be incomplete. /TRRL/
