The invention discloses an urban rail transit elevated structure safety state evaluation method, and relates to the technical field of urban rail transit elevated structure safety evaluation, and the method comprises the following steps: 1, planning and preparation; step 2, detecting the straightness of the track; 3, track flaw detection is carried out; step 4, track load bearing detection; and 5, the detection result is analyzed and evaluated, and the step 2 comprises the substeps that the prepared flatness detector is placed at the position to be detected, the flatness and the curvature of the track are detected, and detection data are recorded. According to the method, the prepared straightness detector is placed at a proper position to detect the track, then the prepared flaw detector is used for performing flaw detection on the track, then the prepared load-bearing detection track car is used for performing load-bearing detection on the track, and finally, all detected data are summarized and analyzed, so that the accuracy of load-bearing detection of the track is improved. And evaluating the safety state of the urban rail transit elevated structure.
