Load transfer behaviour of a tapered rigid pile / J. Liu in Géotechnique, Vol. 62 N° 7 (Juillet 2012) 

Public ISBD [article]  in Géotechnique > Vol. 62 N° 7 (Juillet 2012) . - pp. 649 –652 Titre : Load transfer behaviour of a tapered rigid pile Type de document : texte imprimé Auteurs : J. Liu, Auteur ; J. He, Auteur ; Y.-P. Wu, Auteur Année de publication : 2012 Article en page(s) : pp. 649 –652 Note générale : Génie Civil Langues : Anglais (eng) Mots-clés : Numerical  modelling  Settlement  Piles  Bearing  capacity  Model  tests Résumé : Based on Mohr–Coulomb theory and the load transfer method, a new method of analysing the load–settlement relation and the axial force distribution model in a tapered pile is suggested. The method proposed in the paper considers the influence of the pile–soil radial interaction on the bearing capacity and settlement behaviour. The calculation results show that the pile–soil radial interaction is strengthened and the bearing capacity of a single pile is increased when the taper angle of a rigid pile is increased. The reliability was verified by two model tests. Calculated results obtained by the proposed method were compared with the test data. The close agreement between the calculated and measured values confirmed that the method is reasonably accurate for analysing the behaviour of tapered rigid piles.
