Analysis of damages to bearing structures of engineering structures for planning resource-saving technologies and their accelerated restoration

Abstract The large-scale study conducted a comprehensive technical inspection of transport infrastructure, covering a representative sample of 139 facilities. The comprehensive nature of the study and the large sample size provided a reliable statistical base for an objective assessment of the technical condition of transport facilities. The main focus of the study was on a thorough diagnosis and analysis of the operational parameters of critical structural components that directly determine the overall structural stability and reliability of the facilities. The study identified and analyzed in detail three key structural components of transport facilities: span structures, supporting elements, and foundation systems. The survey methodology used was based on a systematic analysis of technical characteristics, which made it possible to determine the current state of the facilities and develop predictive models of their future operational reliability. Based on the data obtained, a fundamental basis was created for the development and implementation of optimized strategies for the maintenance and modernization of transport infrastructure, taking into account the specifics of each structural element.
