✦ Synopsis

This paper develops approximations for the settlement interaction factors between two dissimilar piles. Via an extensive parametric study using the computer program GEPAN, approximations are developed for interaction factors for piles having dissimilar diameters but equal lengths, piles having dissimilar lengths, and for piles having dissimilar ground conditions at the pile tips. Correction factors are then given to allow for the effects of piles stiffness and length-to-diameter ratio. The approximations may be employed in analyses for group settlements to allow for the case where not all piles in the group are identical.

## Abstract This paper, under the assumption that the pile–pile interaction showed elasticity, analyzed the pile–pile interaction between two dissimilar piles in layered soils using the shear displacement method and taking the sheltering effect into account to modify the conventional interaction fa
