Engineering buildings and structures are objects of increased responsibility. Under certain conditions, buildings and structures are subjects to negative impacts caused by various environmental factors (activation of faults, earthquakes, erosion, freezing, etc.) and technological factors. During operation, it is necessary to control the technical condition of the object and the existing dynamic effects, possibly danger, for the structure and for its parts. The basis for the development of the control method is the results of research devoted to the study of the dynamic effects arising in the dams and the structures hydroelectric power station. This paper shows the results of the analysis of the obtained seismic materials from seismic stations near the Novosibirsk hydroelectric power station and at a distance of about 16 km from it. From the recorded seismic vibrations, signals were identified, the sources of which are the technogenic effects of the operating equipment of the Novosibirsk hydroelectric power station. The possibility of tracking changes in operating modes of hydraulic units at a great distance from the object itself is shown. Shown is the transformation of the received signal by the noise subtraction method to improve the signal-to-noise ratio. |
