Complexity of geological terrain built demands different level of research in order to obtain all necessary characteristics for the establishing of connections between the structure of the objects and the terrain. Frequent changes of rocks in vertical profile and their irregular settling related to creasing of the terrain during geological history makes choosing representative parameters harder. Layers of similar characteristics that are interconnected are separated into geological environments by taking medium values of the parameters within that environment.
During the research, for the purpose of constructing of the silos objects, boreholes were drilled in the axis of each silos to a depth of 10.0 m. In a small area, there is a complex structure of the terrain, which, in addition to changes in the lithological composition, is also dictated by tectonic activity. Directly in the hinterland of the research conducted with boreholes, there is an open terrain profile with a height of about 6.0 m. By connecting the layers from the investigation works and the open profile on the terrain, a clearer picture of their position on the narrow part of the terrain was obtained.
Frequent changes of layers of marly rocks and sandstones and their synclinal deposition demanded separation of certain geological environments with layers of the same characteristics. In addition to taking samples for laboratory tests, field tests of the solubility of marly rocks in the void at different temperatures were also conducted. In parallel with the samples from the investigation works, samples from the open terrain profile were examined. The results showed a shorter dissolution time of marly rocks from the open terrain profile compared to the same rocks taken from the core of the borehole.
