With the advent of ever-growing urbanization and industrialization, there exists a requirement for heavy infrastructures that can retain heavy earth masses and are sustainable in its functioning. The conventional earth mass retention methods using rigid retaining walls are not preferred for most of the projects, as they are expensive and are time-consuming for the construction when compared to the recently developed methods of earth mass retention by Mechanically Stabilized Earth (MSE) structures. MSE walls having large height when constructed in a single tier, often require a huge volume of excavation and an effective land area which is impossible to attain every time. Therefore, the most suitable alternative is to construct it in a tiered fashion. The tiered MSE walls can tolerate large differential settlements without distress, give a sound performance, are aesthetically appealing, are cost-effective, convenient, and provide simplicity in construction. However, the configuration of such walls may present several engineering challenges that have not been covered by the conventional design methods and calculations. This study aims to assess the performance and response of a multi-tiered 12 m high (H) MSE wall and compare it with a single-tiered MSE wall through numerical solutions based on finite element modeling. From the outcomes of this study, it is found that the normalized maximum lateral displacement of the facing of the wall (Δ/Η) is 5.4% and 1.71% in the single-tiered and three-tiered wall system respectively. Also, the factor of safety in three-tiered and single-tiered wall systems observe a growth of 9.4% and 8.4% respectively when the reinforcement length is increased, which establishes the improved performance of the tiered MSE walls and justifies its usage in place of single-tiered MSE walls.
