Abstract. The purpose of research is to study the Sirko ravine, including the analysis of the deformation of buildings and structures, observations by the method of the Earth's natural pulse electromagnetic field to determine the possibility of the development of landslide processes on its slopes.
The study of the Sirko ravine and the adjacent territory was carried out by means of reconnaissance observations, during which the sides of the ravine were described, an analysis of its development, the presence of drainage, water supply systems and the absence of a drainage system, as well as the prospects for its further use. The factors causing the development of landslide processes are the phenomena of soaking due to precipitation and leaks from the water supply system and the absence of storm drainage and sewerage systems.
The main deformations of buildings and structures on the sides of the ravine are considered - the development of cracks on the walls of buildings, fences of asphalt and concrete pavements. Photo documentation is presented, confirming their development. The comparison of the Sirko ravine with the disturbances of the Serednoprydniprovskyi megablock is carried out. It is shown that the strike azimuth of the Sirko ravine coincides with the strike azimuth of the deep fault of the Serednoprydniprovskyi megablock.
To assess the degree of landslide hazard of its slopes, the express method of observation of ENPEMF was chosen. The observations were carried out at the top of the ravine in the area of Gagarin Ave, as well as in the area of the widest part of its thalweg.
The results of observations carried out by the method of the Earth's natural pulse electromagnetic field along two profiles traversed across the strike of the ravine thalweg, which indicate the possible development of landslide deformations of its slopes. These research will help prevent possible deformations of buildings and the development of landslide processes arising from the soaking of its slopes during the development of the slopes of the Sirko ravine.
Keywords: landslide-hazardous processes, deformations of buildings, slopes, natural pulse electromagnetic field.
