A numerical model incorporating a three-parameter dilatant nonlinear incrementally elastic soil model was used to analyze three well-controlled full-scale geosynthetic-reinforced soil (GRS) retaining wall tests. The three tests were conducted to examine the effects of facing rigidity and reinforcement length on the performance of GRS retaining walls subject to central loading (far from the facing panel). It is shown that the numerical model is capable of accurately simulating the behavior of the three tests under service loads, in particular, their sensitivity to facing rigidity and reinforcement length. The validated numerical model was then used to conduct a comparative analysis on four GRS retaining walls subject to front loading (adjacent to the facing panel). The GRS retaining walls comprised four different types of facings having different degrees of rigidity. The results of the comparative analysis are considered useful as a guide for selecting the proper facing rigidity of GRS retaining walls subject to front loading.
