Abstract: The use of continuous geosynthetic inclusions is involved in traditional soil reinforcing techniques such as geotextiles or geogrids, which are strong in tensile resistance. They protect the environment and promote a stronger planet by conserving energy and the earth’s resources through the production of durable and sustainable structures. In the present investigation, a numerical analysis is performed to understand the behavior of a square footing resting on geogrid reinforced soil. The numerical simulations were carried out using a three-dimensional FEM software, PLAXIS 3D. The numerical model was systematically validated with the results obtained from experimental studies. The effect of various factors such as embedment depth of first layer, spacing between consecutive layers and the multi-layers of the reinforcing elements are studied. It is observed that, four numbers of geogrid elements give the maximum bearing capacity ratio of 3.51 for an optimum depth of first layer and the spacing of 0.25B. © 2020, Springer Nature Singapore Pte Ltd.
