Numerical Investigation Of Rigid Inclusion-reinforced Soils Under Shallow Foundations

Abstract
This study presents a numerical investigation into the behavior of a compressible soil reinforced with a load-transfer platform (LTP) and rigid inclusions beneath shallow foundations. The primary objective is to quantify the effectiveness of these reinforcement techniques by analysing settlement evolution both directly under the footing and within the LTP. The numerical model was developed for three scenarios: natural ground, ground reinforced only with an LTP, and ground reinforced by the combined LTP and rigid-inclusion system. The results indicate that the LTP efficiently redistributes stresses and mitigates settlements, while the rigid inclusions facilitate a more direct load transfer to deeper strata, thereby markedly enhancing foundation stability and overall performance. These findings underscore the merit of integrating both techniques in shallow-foundation designs on weak bearing soils.
