ABSTRACT: A framework for analyzing torsionally loaded piles in elastic, multi-layered soil is developed using the variational principle of mechanics. The total potential energy of the pile-soil system is minimized to obtain the differential equations governing the pile and soil displacements. Closed-form solutions are obtained for the angle of twist and torque in the pile as a function of depth. The analysis explicitly takes into account the three-dimensional pile-soil interaction and produces results within seconds. The results match well with the existing solutions and with those of finite element analyses.
RÉSUMÉ: Un cadre d'analyse des accouplements élastiques chargé des piles en élastique, multi-couches du sol est développé en utilisant le principe variationnel de la mécanique. Le potentiel total l'énergie de la pile et le sol du système est réduite au minimum afin d'obtenir les équations différentielles régissant le tas et déplacements du sol. Forme fermée solutions sont obtenues pour l'angle de torsion et le couple dans le tas comme une fonction de profondeur.
