Indian geotechnical journalSummary: The study introduces an analytical analysis of a group of floating granular piled rafts. The formulation employs the Mindlin and Boussinesq equations to estimate settlements for forces in the interior and on the surface of the continuum. The analysis focuses on several normalized parameters, including the settlement influence factor (SIF) for the top of the granular piled rafts (GPRs), the interaction factor, the normalized shear stresses along the granular pile (GP)—Soil interface, the fractional load shared by the raft, the fractional load shared by the GP, the fractional load transferred to the GP base, and the contact pressure distribution underneath the raft. The normalized shear stresses (NSS) along the GP-soil interface describe the shear stresses at different depths below the GP. The percentages of load shared by the raft and the GP and the fractional of load transferred to the GP base provide insights into the load distribution in the system. Finally, the contact pressure distribution underneath the raft indicates the pressure distribution on the soil surface. Overall, the analysis of these normalized parameters provides valuable insights into the behavior of the GPRs system under different loading conditions. These insights can be used to optimize the design and performance of such systems in various geotechnical applications.
