This Paper presents an infinite layer method for the analysis of the settlement interaction between piles embedded in layered soil. In this method, the soil, which can have properties varying with depth, is divided into a number of infinite layers whereas the pile is divided into the same number of solid bar elements, which deform as a rigid section in the horizontal plane. Based on the single pile model, the increase in settlement of each pile due to interaction with the adjacent pile was calculated by an iteration procedure and is expressed in terms of an interaction factor. The influence of the layered soil, pile spacing and pile stiffness on the interaction effect is also examined. Assuming that the principle of superposition is applicable, the interaction between piles in a pile group can then be easily evaluated. The effect of the rigidity of the pile cap on the load distribution among the piles and the settlement of the foundation system has also been investigated. L'article presente une methode po...
