探地雷达在大佛寺无量桥密实度探测中的应用

Application of ground penetrating radar in detecting density of Wuliang Bridge

探地雷达作为文物建筑检测与修复中一种新型探测技术,具有无损性、便捷性和有效性的优点。通过探地雷达在无量桥底座密实度探测中的应用,得出了无量桥的隐患分布点为:东桥台侧墙、上方经幢及桥拱券,其中安全隐患的根源是渗水和水土流失。探测结果证实了探地雷达在检测不可移动文物方面的可行性和有效性,为不可移动文物的日常保护管理和维护提供了科学的量化数据,也为研究、分析和评估不可移动文物的整体安全性提供了参考。

The ground penetrating radar,a new-fashioned type of detection technology in the detection and repair of cultural relics,embodies the advantages of non-destruction,portability and effectiveness.By applying the ground penetrating radar to detect regional density of the Wuliang Bridge foundation,safety hazard distribution points of the Wuliang Bridge are the side wall of the east abutment,the top of the stone pillar,and the bridge arch,for which water seepage and soil erosion are to blame.Thus,detection results have proved feasibility and effectiveness of the ground penetrating radar in detecting immovable cultural relics and provided scientific quantitative data for routine protection management and maintenance,and also offeredreferences for researching,analyzing and evaluating the overall safety of immovable cultural relics.
