J. Murray, Auteur ; J. D. Geddes, Auteur Année de publication : 2007 Article en page(s) : pp. 417-431 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Anchors Failure Model tests Plasticity Sands Soil-structure interaction Résumé : The passive resistance of inclined anchor plates in sand is examined. Laboratory experimental results are presented for the ultimate passive resistance, and the corresponding displacements, of rectangular anchor plates pulled at angles of inclination between the vertical and the horizontal through very dense sand. The results of ultimate passive resistance are compared with theoretical solutions based on the upper and lower bound limit theorems of soil plasticity. A general lower bound solution for a strip anchor pulled at various angles of loading cannot be readily formulated, and only a poor lower bound solution for the case of horizontal loading is determined. However, it is shown that provided interface friction is taken into account, upper bound solutions for a strip anchor compare favourably with the experimental evidence. Good agreement is shown between the upper bound solutions and the equivalent free surface stress characteristic solution, and experimental data, of Neely et al. (1973) for the horizontal translation of anchor plates in medium dense sand. Comparison is also made between the experimental results of this Paper and the finite element approach of Rowe & Davis (1982) for anchors pulled horizontally through an assumed elastic-plastic soil.
