Abstract
The technical condition of bridge structures in the form of farms used for railway traffic is the subject of wide scientific discussions at present. Ensuring this technical condition is a rather significant scientific problem, the solution of which is now becoming increasingly practical. Obviously, one of the most effective tools for managing this technical condition of such structures is the monitoring of engineering structures. A brief technical and operational analysis of railway farms was carried out in the article, highlighting the main problems of their maintenance. The existing monitoring systems (subsystems) were reviewed with a brief description of their operating principles. Proposals for improving existing solutions and approaches to monitoring are described. The relevance of considering this issue is especially important when justifying the optimal number of controlled parameters. This question constantly arises when design documentation undergoes state examination, as well as when communicating with the customer when justifying costs. It is especially important at the stage of developing a monitoring program to take into account the need to analyze the structure from the point of view of its representation by the monitoring object. Obviously, this requires a transition from the subjective determination of control points based on an ideal structure model to strict mathematical dependencies. The condition of the structure in this case, characterized by the number and types of defects, as well as an assessment of permanent and temporary impacts. As an example, data are given on the survey of two bridge structures for a railway with spans in the form of trusses.
