Development of a methodology for assessing the effects of military operations on deformations and the state of stability of the engineering structures of the Dnipro HPP, Kaniv HPP, and Dniester HSPP.
popup.description2
Phase 2 of the project ‘Construction of thermohydrodynamic models of deformations of the Dnipro and Kaniv HPP dams for 2020-2023 and determination of the influence of the natural geodynamic background on the deformation field of dams based on GNSS data from Geoterrace stations’ confirms the hypothesis that natural and anthropogenic factors influence the deformation of dam blocks. The developed annual statistical models of spatial deformations demonstrate that the displacement of structural elements is caused by the natural geodynamic background, temperature fluctuations and water levels in reservoirs. Instead, the abnormal deformations are the result of man-made stresses that may occur as a result of military operations.
To achieve the project results:
• Databases of measurements of GNSS sensors, robotic total stations, geotechnical sensors, weather stations, and water gauging stations of the Dnipro, Kaniv HPPs and Dnister PSPP for 2020-2024 were created.
• The data from the Geoterrace GNSS network were processed and time series of daily station resolutions were generated from 2020 to 2024 in Ukraine.
• A map of deformations of the territory of the Dnister PSPP based on the results of seasonal GNSS observations from 2020 to 2024 and the dams of the Dnipro and Kaniv HPPs was created.
• The thermohydrodynamic models of dam deformations were built using the developed software, which allows determining the coefficients of dependence of horizontal and vertical displacements of the dam crest on the temperature change parameter.
The data analysis in the next stage will make it possible to assess the impact of the explosions caused by military operations on the stability of the Dnister slope of the Dnister PSPP and on the deformation field of the dams of the Dnipro and Kaniv HPPs. The developed system for assessing the impact of military operations on the deformation of these hydraulic structures will facilitate the assessment of their safety and reliability, as well as
