摘要
不可移动文物的结构及构件变形是评估其整体结构安全性的重要指标。不可移动文物的变形检测技术具有面向的结构类型各异、检测环境复杂且非接触要求高的显著特点。对于不同应用场景下,各种检测技术的正确选择是保证现场变形检测的实施可行性和结果可靠性的重要前提。针对不可移动文物变形检测实践中常见的检测技术包括线锤检测、全站仪检测、三维激光扫描仪检测、数字图像法、近景摄影测量和倾斜摄影测量等,对各类变形检测技术的具体应用情况、实施案例进行了阐述,并对各类检测技术的优缺点及适宜的应用场景进行对比,为不可移动文物变形检测的现场实施提供参考。
For immovable cultural relics,structural and component deformation are important indicators to evaluate their structural safety.The deformation detection technology of immovable cultural relics has its own characteristics:different structure types,complex detection environment and high non-contact requirements.For different usage scenarios,the correct selection of various detection techniques is an important prerequisite to ensure the feasibility and effectiveness of on-site deformation detection.In view of the common detection technologies in the deformation detection practice of immovable cultural relics,including line hammer detection,total station detection,three-dimensional laser scanner detection,digital image method,close-range photogrammetry and tilt photogrammetry,this paper describes the specific application and implementation cases of various deformation detection technologies,and compares the advantages and disadvantages of various detection technologies and suitable application scenarios.It provides reference for the on-site implementation of deformation detection of immovable cultural relics.
