Abstract

A key factor in geotechnical engineering that has a direct impact on foundation stability and structural safety is the bearing capacity of sandy soils. Low bearing capacity and high settlement are common characteristics of loose or medium-dense sands that might jeopardise building projects. This study examines how grouting procedures might increase bearing capacity and decrease settlements in sandy soils. Using the Mohr–Coulomb constitutive model in a finite element framework, the study combines numerical simulations with laboratory-scale model tests. Plate load tests were used to determine bearing capacity and settling after cement-sand grout was injected into loose sand specimens in laboratory studies. The behaviour of untreated and grouted soils was modelled using numerical models, which shed light on load transmission processes, deformation patterns, and stress distribution. The findings show that grouting significantly increases bearing capacity and decreases settlements, and numerical calculations support the experimental findings. In order to assist safer and more effective foundation design, the study offers a framework for optimizing grouting techniques in sandy soils.
