THE METHOD OF SEISMOACOUSTIC MONITORING OF THE INFLUENCE OF THE EXPLOSIVE WAVE ON CRITICAL INFRASTRUCTURE OBJECTS

Abstract

Seismoacoustic monitoring of critical infrastructure objects is a set of mode observations, and the mode of the observations themselves and the spectral parameters of the object under investigation depend on the goals pursued by this experiment. There can be many such goals, but the main goal for assessing the state of critical infrastructure objects is considered in the work. These are the dynamics of changes in the spectral characteristics of the object taking place in the research object and the detailed evaluation of the parameters characterizing the object. Seismoacoustic monitoring of critical infrastructure objects is implemented in seismoacoustic monitoring systems with the aim of predicting the dynamics of the state of the research object. This article proposes a new effective model for analyzing the impact of blast waves on the condition of critical infrastructure objects, the natural frequencies of which lie in the seismic and lower part of the acoustic frequency ranges, based on monitoring their dynamics. A new method for identifying the state of such objects is proposed. A non-traditional model of the natural background of the monitoring object in the form of a superposition of Berlage pulses is proposed. Such a model makes it possible to estimate such an important parameter in the description of the object as its quality factor, the dynamics of which can give an idea of its structural changes. The proposed model can be used in automated monitoring systems.
