Assessment of Geogrids for Soil Reinforcement in RE Wall Applications

Abstract

The Reinforced Earth (RE) walls have become known as an efficient and cost effective solution for earth retaining structures in various transportation and infrastructure projects. Geosynthetic Geogrid are one of the significant reinforcement materials used in RE wall systems due to their high strength, flexibility, durability and excellent soil reinforcement interaction characteristics. This study reviews the application of geogrid reinforcement in RE walls and the findings indicate that geogrid reinforced walls provide improved settlement behavior, enhanced stability and reduced lateral earth pressure compared to conventional retaining systems.
