MONITORING OF DEFORMATION PROCESSES OF THE ELEMENTS OF ENGINEERING STRUCTURES OF HYDRAULIC FACILITIES
Abstract
Monitoring the technical condition of hydraulic facilities is crucial for ensuring their safe operation. This process usually involves monitoring environmental variables (e.g., concrete dam levels, temperature, piezometer readings), as well as geometric and physical variables (deformation, cracking, filtration, pore pressure, etc.), the long-term trends of which provide valuable information for facility managers. Research of the methods for analyzing geodetic monitoring data (manual and automatic) and sensor data is vital for assessing the technical condition and safety of facilities, especially when applying new measurement technologies. The age of hydraulic structures in Ukraine is 50-60 years and more, and their technical condition has deteriorated due to long-term operation. Their technical capabilities and reliability have decreased due to improper maintenance. In addition, insufficient consideration of environmental factors during operation has contributed to a decrease in the reliability of these structures.
Most reservoirs and hydroelectric power plants were built in the mid-20th century and have been under constant operation. Due to significant operational life, negative changes often occur in their technical condition. Atmospheric, chemical, and other aggressive factors also contribute to the destruction of hydraulic facilities and their elements in water. This can lead to serious damage to both the facilities and the elements of hydraulic systems dependent on them. An additional negative impact factor on the condition of hydraulic facilities in Ukraine is missile and drone shelling and other damage as a result of military operations. Therefore, there is a need to develop a device that can be used when monitoring relative static and variable deformation, plasticity, and creep of samples from various elements of engineering structures, materials, elements, and assemblies in hydraulic engineering, construction, and industry.
