Deterioration of a wall complex constructed of reinforced earth / G. E. Blight in Géotechnique, Vol. 39 N°1 (Mars 1989) 

Public ISBD [article]  in Géotechnique > Vol. 39 N°1 (Mars 1989) . - pp. 47 –53 Titre : Deterioration of a wall complex constructed of reinforced earth Type de document : texte imprimé Auteurs : G. E. Blight, Auteur ; M. S. W. Dane, Auteur Année de publication : 2007 Article en page(s) : pp. 47 –53 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Case  history  Reinforced  soil  Retaining  walls  Deterioration  Field  tests Résumé : A gravity separation plant at a mine on the west coast of South Africa is flanked by a complex of reinforced earth walls having a maximum overall height of 41 m. Eighteen months after construction had been completed, it was discovered that the galvanized reinforcing strips were deteriorating as a result of galvanic corrosion caused by the aggressive nature of the backfill. The process of deterioration was monitored until the walls were demolished and rebuilt 8 years later. The progressive deterioration of the wall complex is described in terms of the reducing strength of the reinforcement and the continuing movement of the wall facings. The results of in-situ measurements of tensions in the reinforcing strips are also presented. The Paper gives an important insight into the process of corrosion affecting steel buried in soil, and also into the behaviour of large reinforced earth walls.
