Abstract
Introduction. A significant number of hydraulic structures (GTS) located on the territory of the Volgograd region are in an accident and inoperable condition. The unsatisfactory technical condition of the GTS has a negative impact on the security of settlements and economic facilities, the ecological condition of the territory, the integrated use of water resources of the Facility.
Object. The object of research is the overflow dam on the Arable Erik of the Kashirinsky water tract.
Materials and methods. The research was carried out using the GPR "Oko-3", equipped with a 2-frequency antenna unit 150 + 400 MHz. Georadolocation survey is a non-destructive research method, which is based on the phenomenon of reflection of electromagnetic waves from surfaces on which electrical properties change.
Results and conclusions. As a result of the georadiolocation study of the overflow dam on the Arable bridge of the Kashirinsky waterway, it was found that voids and pronounced soil decompression were not found to be critically dangerous for the hydraulic structure. The studies allowed to identify and localize inhomogeneities in the body of the dam, expressed in areas of disturbed soil structure in the body of the dam, as well as local areas of increased soil moisture. The use of non-destructive testing methods, including the use of such modern equipment as the GPR "Oko-3" with a 2-frequency antenna unit 150 + 400 MHz allows for a high degree of accuracy to carry out a survey of hydraulic structures.
