Scientists from the Institute of Petroleum Geology and Geophysics SB RAS have created a unique method that allows one to predict the appearance of cracks in buildings and foundations. The technology is based on the analysis of micro-oscillations and has already been successfully used in practice.
The method developed by specialists from the Institute of Petroleum Geology and Geography SB RAS uses the principles of microseismic – analysis of micro-oscillations that are constantly present in the ground and structures. Using special sensors that can detect fluctuations from three centimeters to nanometers, scientists can detect even microscopic defects in buildings.
“Each structure has its own unique resonance,” explain the developers. – If a crack appears in the structure, the vibration frequency changes. Our sensors not only detect these changes, but also pinpoint the location of the defect.
The technology has already been tested on real objects. In Norilsk, for example, scientists predicted the appearance of a crack in the wall of a building several days before its formation. The method is now used to monitor more than 100 objects throughout Russia, including hydroelectric power plants and residential buildings.
The new method can significantly improve the safety of buildings and structures. In the near future, scientists plan to create a hardware and software complex for mass application of the technology, which will make it available for widespread use.
