Role of Geogrid reinforcement and its diverse applications in the geotechnical engineering and allied fields: a-state-of-the-art review

Soils and geosynthetics are terms used interchangeably whenever the physical and mechanical properties of the soil are unlikely to sustain the load coming over it. Several studies have been undertaken to determine the benefits of using geosynthetic products instead of conventional procedures such as stone columns, jet grouting, soil nailing, and so on. As far as geotechnical applications are concerned, geogrid is the most widely utilised polymeric product. This paper provided an overview of geogrid's numerous applications, including pavements, airport runways, railroads, building foundations, MSE walls, bridge embankments, and landfills. Furthermore, this bibliometric analysis has revealed the important laboratory model experiments done on geogrids as well as numerical finite element and finite difference model analysis. An overview of several case studies involving geogrid reinforcement in large projects was also documented; the review also discussed the present trends and opportunities for future development of new geogrid reinforcement technologies within the same section of the literature collection to have better clarity for comparison.
