The problem of accurate prediction of deformations of reinforced soil structures under serviceable loading is discussed in this paper. First, a short overview of existing guidelines and methods is presented. Second, an analytical approach developed in IBW PAN to calculate horizontal and vertical deformations of such structures is described. Third, results of the verification of the proposed methodology are discussed. The modeling approach is validated against measured results from a literature review and an original laboratory program. Experimental studies under laboratory conditions were carried out to evaluate the accuracy of the proposed methodology. A model of a reinforced soil (RS) wall with a height of 0.5 m was constructed at a geotechnical laboratory and subjected to external loading. Horizontal deformations of the model RS wall were investigated at the end of construction and during the surcharge application (post-construction displacements). A theoretical analysis of the experimental results is elaborated on. A comparison of theoretical and experimental values of deformations is presented. The main conclusions are pointed out.
