The influence of the compaction-induced stress (CIS) is experimentally, numerically and analytically evaluated on the behavior of reinforced soil walls (RSWs), under working stress conditions. Experimental studies have been carried out to evaluate the effect of the compaction condition at the back of the block facing on the behavior of geosynthetic reinforced soil walls using three large-scale geosynthetic-reinforced soil walls constructed at the COPPE/UFRJ Geotechnical Laboratory. The numerical analyses have been carried out using the two-dimensional finite difference computer program FLAC to verify the influence of the compaction modelling procedure at the end of construction as well as post-construction performance of a full-scale geosynthetic-reinforced soil, GRS, segmental wall under surcharge loading. Two procedures for modelling the CIS found in the literature were employed in the analyses. Moreover, the calculated values using two design methods have been compared to the measurements and numerically calculated maximum reinforcement load, Tmax, to evaluate the prediction accuracy of these methods when the value of the CIS is relevant.
