The present dissertation’s objective is to provide a comparative analysis of different methods used for pile group settlement prediction. Firstly, a literature review was made, considering empirical, semi-empirical and theoretical methods, including Boundary Element Method proposed by Poulos, finite layer method, developed by Southcott and Small, fictitious piles proposal, described by Ming and Long-Zhu and Winkler approximation based method by Mylonakis and Gazetas. Then, the results of instrumented pile load tests provided by Cooke and Price were analyzed. The deformation field around a loaded pile was examined and the interaction mechanism between the piles within a group defined. As a result of this analysis, the concentric cylinder model was considered acceptable for displacement field representing. Also, it was found that small pile group settlement could be obtained using a superposition of the displacements caused by one loaded pile. In case of large pile groups, especially consisting of long piles, the interaction factor superposition method is not directly applicable, causing settlement superestimation. To compensate this effect, an increase of elastic moduli of soil has been used by various authors. As the proposals of this type have been criticized, other proceedings that account for complex pile - soil interaction have been created.
