Abstract

In recent years, the use of geosynthetic reinforced soil walls in back-to-back (BTB) configuration has been increasing in roadway and railway construction. In this paper, the failure mechanism of geosynthetic-reinforced soil walls was examined using the discrete element method based numerical investigation. The discrete element model adopted was first validated using the results of 1-g model tests. The validated discrete element method-based numerical model was used to further investigate the failure mechanism of back-to-back walls with different boundary conditions. The results were then compared with the failure mechanisms defined in the FHWA design guideline.
