Design & Study of Reinforced Earth (RE) Panel

The present study entitled “Design & Study of Reinforced Earth (RE) Panel” focuses on the analysis, design, construction methodology, stability evaluation, and performance assessment of reinforced earth wall systems. The study includes detailed literature review, understanding of reinforcement mechanisms, construction procedures, reinforcement strip behavior, precast wall panel systems, stress analysis, displacement analysis, and numerical modeling using PLAXIS 2D software. The reinforced earth structure considered in the study was analyzed under highway loading conditions as per IRC: 6-2014 and stability criteria recommended in BS 8006:1995. The analysis and design of the reinforced earth embankment were carried out using Excel calculations and PLAXIS 2D finite element software. The study included evaluation of external stability, internal stability, lateral earth pressure, reinforcement tension, stress distribution, pore pressure, displacement behavior, shear force, and bending moment. The results obtained from the study indicated that the reinforced earth structure is stable and safe under all loading conditions. The maximum reinforcement tension obtained was 52.86 kN, maximum stress developed in the structure was 200 kN/m², extreme active pore pressure was 60 kN/m², extreme total principal stress was 91 kN/m², and total displacement was 18 × 10⁻³ mm. The displacement and stress values remained within permissible limits, indicating satisfactory structural performance. The study also highlighted the advantages of reinforced earth wall systems such as rapid construction, flexibility, reduced maintenance, improved seismic resistance, economy, and better aesthetics.
