Titre : Group interaction effects on laterally loaded piles in clay Type de document : texte imprimé Auteurs : S. S. Chandrasekaran, Auteur ; A. Boominathan, Auteur ; G. R. Dodagoudar, Auteur Année de publication : 2010 Article en page(s) : pp. 573-582 Note générale : Géotechnique Langues : Anglais (eng) Mots-clés : Efficiency Lateral load Pile group Soft clay Soil-pile interaction Bending moment Index. décimale : 624.1 Infrastructures.Ouvrages en terre. Fondations. Tunnels Résumé : This paper presents the results of static lateral load tests carried out on 1×2, 2×2, 1×4, and 3×3 model pile groups embedded in soft clay. Tests were carried out on piles with length to diameter ratios of 15, 30, and 40 and three to nine pile diameter spacing. The effects of pile spacing, number of piles, embedment length, and configuration on pile-group interaction were investigated. Group efficiency, critical spacing, and p multipliers were evaluated from the experimental study. The experimental results have been compared with those obtained from the program GROUP. It has been found that the lateral capacity of piles in 3×3 group at three diameter spacing is about 40% less than that of the single pile. Group interaction causes 20% increase in the maximum bending moment in piles of the groups with three diameter spacing in comparison to the single pile. Results indicate substantial difference in p multipliers of the corresponding rows of the linear and square pile groups. The predicted field group behavior is in good agreement with the actual field test results reported in the literature.
