heal.abstract	The current design approaches for reinforced earthfill structures are limit state methods, which involve nominal loads being increased by stated load factors, and material strengths reduced by stated partial material factors. Advanced numerical analyses do not suffer from the above shortcomings and have been used to assess the accuracy of the more approximate calculations. A case study of reinforced soil retaining wall sections is analysed using limit equilibrium methods. The behaviour of the walls for the same arrangement of reinforcements is examined using advanced numerical methods. Numerical analyses were performed using the finite difference program FLAC and the finite element program PLAXIS while analyses based on the codes of practice were performed using Excel calculation sheets and the SLIDE program. The global stability checks are confirmed by the observed performance of the walls when analysed using numerical methods while the latter result invariably in smaller tension forces developed in the reinforcement. Convergence in the displacement calculations and forces in the reinforcement is observed for both numerical methods of analysis. © 2007 Civil-Comp Press.	en
