Large-scale Bridge Distortion Measuring Technique Discussion

Abstract

Deformation Measurement is a large measuring deformation monitoring of bridge and the bridge is structurally controlled an important part of long-term monitoring and diagnosis of health. The article comprehensively analysis contemporary advanced measuring equipment and new technology, such as GPS global positioning system, surveying robots and measuring digital close-range photogrammetry system, and then formulates advanced and reasonable surveying measurement, make up the corresponding data processing software to create real-time monitoring system and large bridges monitoring data analysis and management system, formed a complete bridge suitable for large deformation measurement theory and techniques to ensure the normal operation of large-scale bridge building and the quality is of great significance.
