Abstract
Elevation monitoring is an important step in the construction process of wide low tower cable-stayed bridge. In this process, it mainly controls the difference between the actual elevation and the design elevation in the cantilever construction process of beam section, and controls the formwork elevation value of each section of beam section construction, In the study of cantilever construction elevation monitoring method, this paper analyzes the engineering background and elevation detection process error analysis, elevation control value selection and elevation linear control analysis, and takes a wide low tower cable-stayed bridge as an example, combined with the actual test results to verify the method. It is concluded that the elevation correction error is controllable and the construction alignment is consistent with the design alignment. The vertical alignment error meets the specification requirements, which can provide reference for the elevation control of similar projects.
