This article presents a numerical approach for modeling of the compaction-induced stresses on the analyses of geosynthetic reinforced soil (GRS) walls. The modeling of the backfill compaction stresses was described and analyses were performed using this suggested procedure. Two distribution loads at the top and bottom of each soil layer were used to simulate the vertical induced stress due to backfill soil compaction. The suggested procedure was validated with the results of a wrapped-faced full-scale reinforced soil wall performed at the Geotechnical Laboratory of COPPE/UFRJ. The results of the simulation using this procedure were compared with another procedure reported in the literature. Parametric studies were carried out to verify the effect of compaction induced stress and surcharge loads on the behavior of GRS walls. Results show that the compaction procedure suggested in the present paper was able to properly represent the measured values of the summation of the maximum tension in the reinforcement and lateral movements. It was verified that the compaction procedure used in the literature overestimated the measured values, and this discrepancy increases with depth and also with compaction effort.
