Opis:
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.

Opis:
The subject of the article concerns the problem of estimating the location of a slip line in a massif with a vertical retaining wall made of reinforced soil, in which the limit state of active pressure was induced. The task is solved experimentally, on the basis of measured unit strains in the reinforcement inserts, with the use of electrofusion strain gauges. The inserts are located in horizontal layers. The slip curve is formed by the points where the maximum normal stresses occur in the reinforcement inserts. This curve cuts off the fragment wedge that is being sought from the plane of the retaining wall. The slip line divides the area of the massif into two zones: active (splinter wedge) and passive, in which the reinforcement inserts are anchored. The test stand is presented, the technique of measuring the deformation of the reinforcement and the method of estimating the location of the slip surface are discussed.

Opis:
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.

Opis:
The publication considers reinforced soil in relation to the construction of retaining walls in communication construction. The basic elements determining the cooperation of reinforcement inserts with the ground centre are discussed, depending on the features characterizing the components of the composite. The method and selected results of tests performed on a massif model with a vertical wall made of non-cohesive ground have been presented. A calculation example is given concerning the internal dimensioning of the reinforcement of the considered massif model, assuming the work of inserts without slipping in the ground centre. The concept of reinforcement co-operation indicator with the ground centre was introduced and a dependence to calculate its value was developed. The values of co-operation indicators: general and partial, concerning individual measurement levels of the model have been presented appropriately.

Opis:
The subject of the article are the layers strengthening the base of the railway track, used in special cases of modernization of the main lines on the Polish State Railways. The construction of a three-dimensional reinforcing mat, also known as a "mattress", is presented. The reinforcing "mattress" is a layer of stone aggregate pre-compressed in an openwork coating made of plastic mesh. The results of the research on vertical displacements of the experimental section established in the railway track with a spatial mat embedded in the substrate are discussed. Vertical displacements were obtained as a function of time in the track subjected to the operation process.
