GEO-MECHANICAL FEATURES OF THE TERRAIN The site prospecting up to 12.0 m depth separates the layers of dikes, loamy clays, dusty sandy clays and sandy clays and clayey muddy dusts, Figure 2. The last two layers can be divided into a dust layer of clay sediments from lower layers of silt materials. Below the layer above the sandy gravel sediments , this prospecting is not registered. The results of site prospecting and laboratory tests have given the information necessary for further geomechanical calculations. Data obtained in the laboratory are somewhat better in relation to the terrain characteristics defined during drilling and core from the recording drillholes. This primarily refers to the layer of clayey dusty sediments with interlayers of muddy material. In order to build these facilities, the certain stability analysis for the coast natural conditions and conditions that will occur provided the construction of buildings was implemented. For clayey dusty sediments, the adopted parameters are somewhat lower due to the presence of muddy components: γ pot. = 9.6 kN/m 2 , φ = 10 0 and c = 8 kN/m 2 , where the following values were obtained: • the natural state with no load, the water level of 83.0 m, Fs = 1.226 • the natural state of the specified load, water level 83.0 m, Fs = 1.112 Given the above analysis to date features of the terrain, dust sediments are favorable for the foundation support struc tures which are planned to ensure the road trunk. For improvement the security of support structures, it is necessary to replace materials with good quality gravel from the river Sava, which in the good conditions of compactness could be a stable support. The replacement of material will prevent the export of finest particles, which would result into the terrain stabilization of embankment. CONCLUSION The investigations, conducted for the purpose of planning the right riverside of the river Sava in Brcko, gave the necessary information about the geological structure and geomechanical characteristics of the terrain. The laboratory testing results are partly differ from the site data obtained during the investigation and mapping the drillholes. The differences are related to the presence of sludge materials in clayey dusty layer that deteriorates its properties. The analysis of stability for the riverside natural conditions and conditions that will occur in construction of buildings, shows that the terrain is located somewhere on the border between the natural balance, so that each new intervention on the ground require more detailed analysis and calculations of terrain stability as well as load of individual layers for foundations of facilities.
