Abstract

In this PhD (doctoral) thesis is made models of rocky massif in real condition which defines the conditions for their application and assessment of the degree of stability. Based on modern methods of research and analysis for calculating the degree of stability, there is done a research models that would be useful for the calculation of stability. The research was conducted at three locations in eastern Macedonia, village Shashavarlija, children resort - Plackovica and one part of the Skopje valley. The observations were performed with an interval of two years and is conducted a method of geoelelectrical sounding. Measurements are performed multiple times on the same section, in order to define the sliding plane, depending on the weather. From the data obtained from geoelectric sounding it can be concluded that the specific electrical resistance of rock masses is fall at a time of increased precipitation of rainfall, especially in dry periods of the year occur relatively high values of the specific resistance, especially in the surface layer. This appearance is normal to expect. The analysis of the specific electrical resistance in the researched section clearly indicates that the sliding plane of the rock masses is characterized by reduced specific resistance in relation to the surrounding rock mass, especially in extremely wet condition. In these conditions, it comes to the intense activation of the process of sliding rock masses. The results are consistent with the basic theoretical assumptions, ie the zone with increased amounts of water has a lower value of the intensity of the specific electrical resistance, although it is the same type of geological environment. The results of these studies indicate that the geoelectric methods can provide useful information in researching the sliding plane of rock mass. This models can be applied in surface mines, in preparation of slopes of working trenches and cuts, in the construction of roads, in determining the stability of the slope of the natural slopes, slopes of river beds, disposal, landfill and other geotechnical structures. Key words: rock massive, sliding plane, specific resistance, geoelectric, stability, deformations, methods for determining stability, factor of stability, landslides.
