The researches of horizontal deformations of laboratory model of road embankment retaining wall constructed with gabion elements were described. The gabions, in other words grid - baskets filled with granular material, located in the rectangular container build from within one of the walls. Remaining part of container is filled with coarse - grained sand imitating the embankment beyond the retaining wall. Were performed three types of gabion walls: wall composed with three gabions (type A); with four (type B) and seven (type C). Individual types constructed in two variants: loose gabions and gabions jointed with steel clips. The horizontal pressure of retaining wall model at the measurement wall of container was aroused using the load with statical vertical pressure. Special construction of container walls enabled execution of horizontal displacement measurements of model, which counted at the unitary horizontal pressure. The test results were presented in form of diagrams of models horizontal pressure, measured at the seven wall levels according to the wall configuration. Were ascertained the horizontal deformation reduction of gabion embankment model with reference to the pattern. The value of reduction depends on dimensions, configuration and arrangement of gabion basket. ...
In the paper were described the research results of in the elastic plastic range work of grid - stone basket model (gabion), making the retaining wall element of country roads embankment. The gabion model was executed in the cuboid form with dimensions in the location plan 0,52 x 0,52 m and 0,42 m height. The gabion model is assembled with shield constructed with hexagon mesh steel grid. The inside of shield is filled with stone material. The object was placed in the special construction container - the walls and the bottom are constructed with the elements, independently deforming. The model of gabion was vertical loaded, with statical central pressure. Were executed the measurements of the vertical and horizontal pressure and also the vertical pressure delivered at the one - parameter type Winkler ground. Were foundated the variable parameters: suppleness of grid coat and the sort of filling stone material. Were ascertained the reduction of pressure at the basis in the range from 15 to above 30 % with reference to the without coat model, making the pattern. Besides, verticale pressure of gabion at the basis suffers reduction moderately diminution of coat suppleness. Presumably, the work of loaded gabion is determined ...
