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. ...
The paper presents the results of research on the suitability of local natural ground for construction of the surface of planned football field, in terms of water permeability and retention capabilitiey. Physico-water properties of silt loam collected from the area of planned football field were tested. Under conditions of very low water permeability of the tested ground in the sub-arable horizon, there is a possibility of persistent considerable moisture content in the planned football field surface after heavy rainfall. Therefore, the football pitch will be damaged, which may make difficult or even prevent football playing and worsen the esthetical values of the football field. In conclusion of conducted field and laboratory analyses it may be stated that granulometric composition, low water permeability and very high water capacity definitely disqualify the natural silt loam in the area of the designed football field as a material suitable for constructing either the carrying layer or the drainage layer of the football pitch. ...
