• Abstract:
  This study investigated the bearing stress imparted by a Mechanically Stabilized Earth (MSE) retaining system. Use of the MSE system is notable for the associated cost efficiency, flexibility, and high deformation tolerance compared to traditional concrete retaining systems. There have been recent cases highlighting the need for substantial foundation strengthening in MSE walls to satisfy bearing capacity requirements. Meanwhile, current methods used for design stress estimation in such flexible structures might be inadequate, as it does not account for many of the features that make an MSE system an attractive option, hence, it is important to study the performance of a full scale MSE system. This research utilized full-scale testing and numerical simulations to examine the mechanical behavior of MSE systems and developed numerical models to simulate the experimental setup.
