探地雷达在古城墙病害探测中的应用
摘要:古城墙由于长年雨、雪水的侵蚀，容易造成城墙内部砖层、土体疏松等病害区域的发生，然而如何确定这些病害的位置、深度、规模等，是非常棘手的问题。探地雷达作为一种无损探测手段，具有探测效率高、分辨率高、结果直观等特点，对探测目标体不会造成任何损伤。结合工程实例，采用探地雷达技术对古城墙顶面进行探测。根据对探地雷达图谱进行处理分析，并选取5处有代表性的雷达图谱进行轻型动力触探验证。结合轻型动力触探验证资料，综合解释分析，提高了查找病害区域的准确性，同时说明探地雷达在古城墙探测中的适用性。
Abstract:Due to the rain and snow erosion for years, the ancient wall is likely to cause lots of diseases area such as loose of brick layer and soil of internal walls, but it is a difficult problem to determine the location of these diseases, depth, size, etc. Ground penetrating radar as a non-destructive means of detecting, has features of high efficiency, high resolution, intuitive results of the detection target without causing any damage. In this paper, combined with engineering examples, using ground-penetrating radar technology to detect the ancient wall top surface. According to the processing and analysis information of GPR,selecting five representative of the radar map to carry out rod detection. Combined with the information of rod detection, carried out a comprehensive analysis to improve the accuracy of finding out disease areas, indicating the usefulness in ground-penetrating radar to detect the ancient wall.
