Geosynthetic reinforced soil (GRS) systems were tested under different loading conditions in order to develop a simplified model for predicting the deformation characteristics of a GRS mass. A simplified preloading-reloading (SPR) analytical model was developed to predict the deformation characteristics of GRS masses subject to monotonic loading and preloading/loading. The SPR model was shown to be able to accurately predict the results obtained from a revised laboratory performance test. The results of this study will be of interest and utility to geotechnologists working with GRS systems.
