The present invention discloses a steel rail super-elevation non-contact measurement method. A bending steel rail, a laser measurer and an A frame are provided in the non-contact measurement process.When operation is performed, a laser measurement instrument is arranged on the A frame and is subjected to level regulation to perform measurement for a bending track, a light beam emitted by the laser measurement instrument is regulated to be perpendicular to the bending track, and a super-elevation value is obtained according to the height difference of the top portion of the track measured by the laser measurement instrument. The measurement data is displayed on a display screen of the laser measurement instrument and can be also downloaded for analysis and processing. The non-contact measurement method is simple and high in measurement precision, and is especially suitable for super-elevation measurement of the bending track so as to greatly reduce the workers' workload and improve theworking efficiency. 本发明公开
