Large-span bridge construction monitoring method
The invention relates to the technical field of long-span bridge construction, and provides a long-span bridge construction monitoring method which comprises the following steps: actually measuring arch rib deformation, main beam deformation and suspender cable force on a construction site; arch rib deformation, main beam deformation and suspender cable force are analyzed and compared with the theoretical calculation values of the arch rib deformation, the main beam deformation and the suspender cable force respectively; according to the analysis result of the bridge under the construction load, the execution content of the next process is fed back. According to construction site measurement and collection data, the state of the structure is subjected to simulation analysis and compared with design data, a straining beam and arch rib stress (strain) or suspender force state and structure linear analysis report of the structure at the current stage is given, the subsequent construction state is predicted, and construction control suggestions are provided. While a target and a decision basis are provided, the construction safety and quality are ensured, and finally, the construction finished bridge state meets the design requirements.
