FIELD: measuring.
SUBSTANCE: invention relates to measuring equipment, to the field of non-destructive testing of technical condition of continuous steel-reinforced concrete span structures and can be used for control and diagnostics of this type of span structures of bridge structures. Method involves action on the span of a temporary load, wherein the stress values are measured at two points: strain gauges are installed in the above support zone of the continuous steel-reinforced concrete span on the lower belt and in the middle of the height of the metal part of the span. Based on the obtained results and their deviation from the reference values, the technical state of the superstructure is determined.
EFFECT: reduction of labour intensity of technical condition diagnostics and improvement of its reliability.
