Abstract
A brief description of natural and artificial influences influencing the stability of buildings and structures is presented. Studying the seismic resistance of buildings and structures designed, under construction, erected, and in operation requires time to wait for seismic activity, which is not permissible; costs of manpower and resources, which is inappropriate. In this regard, a working hypothesis has been put forward that by artificially acting on soils with the help of detonation wave energy, it will be possible to induce vibrations, with the help of which it will be possible to study the behavior of building structures put into operation, the entire building and structure as a whole. The goal is set: - to investigate the behavior of structures under construction and in the operation of buildings and structures that perceive artificial vibrations caused by the detonation unit by acting on soils. To achieve this goal, tasks have been identified. A detonation (blast) wave is taken as a "tool" for force action. The theoretical foundations of the experiment are briefly presented and the developed scheme of a detonation tube and a shock wave with a general view of the installation causing detonation wave energy. A brief technique for carrying out field experiments is presented.
Highlights
Studies in [1, 2] are devoted to the numerical solution of the problem of transverse and longitudinal vibrations of buildings and structures based on a plate model developed within the framework of the bimoment theory of plates
To register the parameters of weak and strong movements of soils, buildings, and structures under dynamic influences, seismic sensors such as SM-3, VEGIK, S-5-S, VBP-3, OSP-2M, APT-1, which are used in coupled with low-frequency and high-frequency galvanometers type GB-III and GB-IV
Records are made on photosensitive oscillographic paper, which is an oscillogram of the measured values after chemical processing
Summary
Studies in [1, 2] are devoted to the numerical solution of the problem of transverse and longitudinal vibrations of buildings and structures based on a plate model developed within the framework of the bimoment theory of plates. In the section of the pipe, at a distance of 1 from the closed end, there is a shock wave - a very narrow, of the order of several mm, zone in which the mixture is compressed to a pressure of Pv = 35 atm. From this compression, the mixture is heated to approximately the temperature tyB = 15000C. Behind the shock wave from the side of the closed end of the pipe, the combustion products no longer rest as a fresh mixture but move towards the open end of the pipe at a speed of about U = 800 m / s.
