Laboratory tests of deformations of retaining wall gabion-element of the country roads embankment

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 ...
