Title

Numerical Modelling of the Behaviour of 3D Geogrid Reinforced Soil Foundation

Authors

Abstract

This paper presents the results of numerical studies carried out on a square footing resting on sand reinforced with three dimensional geogrid using Plaxis-3D software. The performance of 3D geogrid reinforced sand bed was compared with the planar geogrid reinforced sand bed and unreinforced sand bed. The foundation soil was modelled by Mohr coulomb model and the reinforcements were modelled using geogrid structural element available in the software. The numerical models of unreinforced sand bed, planar geogrid reinforced sand bed and 3D geogrid reinforced sand bed were validated with the laboratory plate load test results. The experimental results and numerical results were found to be in good agreement with each other. Using the validated model, parametric studies were carried out to quantify the effect of various parameters on the performance of reinforced soil. The results showed that 3D geogrid reinforced sand bed performed better than conventional planar geogrid reinforced sand bed. Planar geogrid with an optimum number of layers improves the bearing capacity of sand bed by 3.7 times compared to unreinforced soil, whereas, of 3D geogrids gives a BCR value of 6.30.
