大桥由于受环境的影响,结构的老化不可避免,因此掌握结构健康状况是大桥养护管理部门非常关键的工作内容。使用准确、全面、科学、安全的方法对大桥桥塔的健康状态进行检测和分析是一项重要的工作。采用摄影测量技术对桥梁的健康状态进行检测,是结构外观检测的一次技术革命,通过建立高清图像档案和结构病害数据库,使桥梁的外观检查直观、详尽、准确、高效和可追溯。这项新技术的应用,改变了外观检测的作业方式,为数字化、电子化、档案化管理桥梁提供了可行办法,解决了大桥养护的技术难题。
Bridge due to the impact of the environment, the aging of the structure is inevitable, so to grasp the structural health status of the bridge maintenance and management department is a very crucial part of the work. It is an important task to use the accurate, comprehensive, scientific and safe method to detect and analyze the health status of the bridge tower. The use of photogrammetry technology to detect the health status of the bridge is a technological revolution in structural appearance inspection. Visual inspection of the bridge is intuitive, detailed, accurate, efficient and traceable through the establishment of HD image files and structural disease databases. The application of this new technology has changed the operation mode of appearance inspection and provided a feasible way for the digitalization, electronicization and archival management of bridges, and solved the technical problems of bridge maintenance.
