    Pile foundations are used on sites with compressible soils. In some cases a pile passes through layers having large differences in soil modulus values. Displacements of a pile toe depends on position, thickness and geotechnical properties of soil layers. Influence of those factors on displacements of the pile has been investigated by the finite element method analysis the axially-symmetrical elastic problem, in the multi-factorial numerical experiment. The computations were conducted for various combinations of the main factors, such as: modulus of elasticity distribution in the three-layered medium and dimensions of particular layers. As the result of the numerical experiment, substantial amount of data was collected. The way to improve understanding of the investigated relationships, was application of a relatively novel exploratory analysis technique: Multivariate Adaptive Regression Splines (MARs). Detailed discussion of the factorial interactions in received MARs approximation is presented in the paper.
