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 ...
The paper presents the results of model tests carried out in a semi-technical scale. Author have been trying to answer the question, how the embankment lifting water made of the ash-slag mixture would behave and what kind of the possible filtration damages would occur in particular parts of the structure. It was verified in the conducted tests whether the applied kind and method of building up the geo-synthetic polymer barrier /GBR-P/ and the draining elements would ensure the safe working conditions of the structure. There were determined in laboratory tests the changes of the filtration curve location in the body of the hydraulic embankment without sealing elements and with the GBR-P screen. The tests revealed, that the furnace waste such as the ash-slag, cannot be used in hydraulic engineering without proper procedures. It may be building in geosynthetic sealing elements and drainage preventing from suffusion and liquefaction. ...
