A preliminary study has been carried out of the effectiveness of a novel form of earth retention system - anchored earth - in providing a more economic method of construction than other techniques currently available. To assess the performance of anchored earth, the results obtained from a model experimental wall, together with data from laboratory and full-scale pull-out tests, were compared with those data from similar tests carried out on an equivalent earth reinforcement system as it has already been established that the latter method of construction is both convenient and economic. The study indicated that the component costs of anchored earth are likely to be considerably less than those of alternative earth reinforcement systems. Moreover the generally better performance in the tests was achieved by the former method. The report describes the proposed TRRL anchored earth system and gives details of the tests carried out and results obtained. (Author/publisher)
