Analysis of laterally loaded pile using the combination of SW model and the imbedding method

摘要

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.
