Scale and other factors affecting the results of pull-out tests of grids buried in sand / E. M. Palmeria in Géotechnique, Vol. 39 N°3 (Septembre 1989) 

Public ISBD [article]  in Géotechnique > Vol. 39 N°3 (Septembre 1989) . - pp. 511 –524 Titre : Scale and other factors affecting the results of pull-out tests of grids buried in sand Type de document : texte imprimé Auteurs : E. M. Palmeria, Auteur ; G. W. E. Milligan, Auteur Année de publication : 2007 Article en page(s) : pp. 511 –524 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Sands  Friction  Research  Reinforced  soil Résumé : Misleading results of pull-out tests have often been reported. Factors such as soil dilatancy or the effects of boundary conditions are usually given as causes. This Paper attempts to group the results of pull-out tests of grids to show a consistent pattern of variation independent of the scale of the test. This has been accomplished by identifying some of the usual causes of misleading results and by considering the grid reinforcement as a succession of bearing elements, buried in the soil, that can interfere with each other. If boundary influences are avoided, the interference between bearing elements is the main factor that affects the results of pull-out tests of grids. It is also observed that, despite its practical advantages, the comparison of a grid to a perfectly rough material, as an upper limit for grid performance, seems not to be the most appropriate.
