Abstract
Bulk hydraulic structures, such as dams and dams of tailings and ash dumps are very widespread and are hazardous production facilities. The article analyzes the existing methods of geodetic monitoring of bulk hydraulic structures, their advantages and disadvantages are considered. For monitoring bulk hydraulic structures, a new technique is proposed, in which the main type of geodetic monitoring is ground laser scanning, which allows the determination of both displacement vectors for individual points and areal deformations that can be analyzed using map algebra. To highlight the surface of the dam, filtering is used according to the molding method, which allows us to clear the cloud of points of laser reflections from vegetation. Since the enclosing dams are long, it is proposed to localize the scanning sites using geotomographic studies, which make it possible to identify areas of structural het-erogeneities in the body of the dam, voids and areas of highly moistened rocks. For visual inspection of hydraulic structures, it is proposed to use unmanned aerial photography, with which you can get a three-dimensional model of the body of the dam. The dam body model can be used for finite element modeling of stresses and filtration processes in the dam body. The article provides a database diagram of the "Dam deformation" software package, which allows you to store complex information about a hydraulic structure and use it to make decisions about the state of the object.
