Mechanically Stabilized Earth (MSE) walls have revolutionized modern geotechnical engineering. From highway underpasses to commercial retaining walls, these composite structures—combining granular backfill with metallic or polymeric reinforcement—offer an unparalleled blend of economy, durability, and aesthetic flexibility. However, the design of an MSE wall is a rigorous, iterative process governed by multiple limit states: internal stability, external stability (sliding, bearing, overturning), and global stability.
