The invention discloses a railway bridge performance evaluation method. The method comprises the following steps: S1, shooting the surface of a bridge to obtain a bridge apparent image; s2, splicing the discrete bridge appearance images into a bridge overall image; s3, acquiring disease occurrence parts, disease features and disease degree data on the whole image of the bridge through image recognition; s4, respectively calculating a bridge static evaluation index and a bridge dynamic evaluation index according to the disease occurrence part, the disease characteristics and the disease degree data; s5, performing result correction on the bridge static evaluation index through the bridge dynamic evaluation index to obtain a corrected bridge fusion evaluation result; and S6, carrying out grading evaluation on the corrected bridge fusion evaluation result. Inspection, detection and structure response detection monitoring indexes are fused and evaluated, and the problem of limitation of a traditional bridge safet
