METHOD FOR MONITORING THE TECHNICAL CONDITION OF THE BRIDGE SPAN Russian patent published in 2022 - IPC G01M7/00 

FIELD: non-destructive testing.

SUBSTANCE: invention relates to the field of non-destructive testing and is intended for monitoring the technical condition and diagnostics of span structures of bridge crossings. The method is implemented by performing periodic or continuous monitoring of the technical condition of the bridge span, including polling the measuring equipment installed on the structures of the structure, converting the information received and transmitting it to the control room, where an automated assessment of the technical condition of the structure is carried out, determined by the results of comparing the measured parameters with pre-calculated and the signal levels entered into the system memory, as well as by the change in time of the control invariant parameters: the ratio of stresses in the upper chords to the stresses in the lower chords; the ratio of stresses in the same type of symmetrical elements of the span; the ratio of the roll-out of the supporting parts to the temperature of the metal structures of the superstructure; the ratio of displacements of symmetrical nodes of the left and right farms.

EFFECT: increasing the reliability and accuracy of determining the technical condition of an artificial structure based on monitoring results.
