Retaining walls have been classified and characterized as structures protecting road or railway embankments against landslides. Particular attention was focused on retaining structures classified as light [1-3, 5-12, 14-24], which include, among others, walls made of gabions. Physical models of the gabion retaining wall, prepared on a laboratory scale, test stand and how to perform spatial deformation tests are presented. The models differed in the number and dimensions of gabions. On the basis of measured horizontal deformations of embankment models with a gabion wall, which were subjected to vertical static pressure at the level of the embankment ceiling, the values of basic strength parameters were determined. In particular, the value calculated: horizontal pressure coefficient, shear strength and modulus of deformation. The variability of the values of these parameters was estimated as a function of variable factors related to the gabion wall configuration (determined by the number and dimensions of gabions) and the value of the external load test.

The subject of the article concerns road embankments made of reinforced soil. The results of the analysis of the effectiveness of the reinforcement of these structures as a function of selected variable factors concerning the soil medium and the parameters of reinforcement inserts are given. The efficiency analysis was carried out on the basis of measurements of the horizontal unit pressure made on a physical model of a soil massif with a vertical wall of reinforced soil. The large-scale model was constructed on a laboratory scale. The article ends with a summary containing conclusions of a cognitive and practical nature.
