ABSTRACT: Beam on elastic foundation (BEF) theory provides an efficient solution for problem of laterally loaded pile. The accuracy of such solution depends upon the characterization of soil-pile interaction. The strain wedge (SW) model provides a theoretical link between the one-dimensional BEF and the corresponding three-dimensional soil-pile interaction. However, the implementation of SW model requires an iterative solution of BEF. In this paper the SW analysis of laterally loaded pile is simplified by the application of imbedding method. The imbedding method is an efficient approach for the analysis of BEF. In the imbedding method the beam is divided into n nodes and the information on shear and moments at adjacent nodes are related through reactions and six imbedding coefficients. Results of study show that the combination of the SW model and the imbedding method provides an efficient approach for the analysis of laterally loaded piles.

RÉSUMÉ: Poutre sur fondation élastique (BEF) la théorie fournit une solution efficace pour le problème de la pile chargés latéralement. La précision de cette solution dépend de la caractérisation de l'interaction sol-pieu. Le coin souche (SW) modèle fournit un lien théorique entre les unidimensionnel BEF et le correspondant interaction en trois dimensions sol-pieu. Toutefois, la du modèle SW exige une solution itérative de BEF. Dans cet article l'analyse de SW pieu chargé latéralement est simplifié par l'application de la méthode de plongement. La méthode de plongement est une approche efficace pour l'analyse de BEF. Dans la méthode de plongement le faisceau est divisé en et les renseignements sur le cisaillement et des moments adjacents sont liés par des réactions et six coefficients plongement. Résultats d'études montrent que la combinaison du modèle SW et la méthode de plongement fournit une approche efficace pour l'analyse des pieux chargés latéralement.
