The finite element procedures are extremely useful in gaining insights into the behavior of reinforced soil retaining walls. In this study, a validated finite element procedure was used with Abaqus for conducting a series of parametric studies on the performance of gabion facing wall with 2m vertical spacing Geo-grid under different surcharge loadings. The performance of the wall was presented with facing horizontal deformation along wall height, and compare to centrifuge model and field measurements. The soil properties include density, Young modulus, Poisson’s ratio, and internal friction angle were among major variables of investigation. At low loading conditions, the impact of increasing density has a significantly greater effect on the deformation of the wall compared to high loads. As the loading increases, the effect of reducing the Young’s modulus on deformations decreases. Moreover, with increasing loading, the effect of deformations due to the decrease in internal friction angle increases, but the rate of this increase decreases. The influence of Poisson’s ratio on the deformation of the walls has decreased with increasing of loading. The results show that by the increase in load, even at a shallow depth, the applied stresses on the soil increase, leading to greater deformation of the soil above the wall, and the maximum magnitude is created at a higher elevation.
