| description | The invention relates to the technical field of bridge test detection, and particularly discloses a strain curve-based prefabricated assembled beam bridge damage identification test method, which comprises the following steps of: arranging a plurality of strain test points on a prefabricated assembled beam bridge to be tested; loading a moving load, and acquiring strain data of a strain section; extracting strain data of each strain section, and performing noise reduction processing on the strain data to obtain a strain influence line of each strain section; judging a longitudinal damage position: judging the longitudinal damage position according to the position change of the intersection point of the strain influence lines with different spans. According to the method, through the section strain influence lines at different spans of the longitudinal beam of the prefabricated assembled beam bridge, error correction and noise reduction processing generated by residual strain influence are carried out on test |
