探地雷达技术在古城墙修缮中的应用
|
摘要
平遥古城墙是我国珍贵的文化遗产。由于古城墙经历年代久远以及近代人为破坏,其内部结构发生了很大改变,目前已有部分马面和墙体出现裂缝,甚至发生了严重的跨塌事故。本文以探地雷达技术的应用为基础,简述了探地雷达在古城墙修缮中的基本原理及应用。通过讨论探地雷达技术对目标体的检测,分析古城墙雷达剖面,得出了城墙内部存在松软土体、孔洞、裂缝等结构缺陷,并给出危险等级,为制定修缮计划提供了可靠的依据。
Pingyao ancient city wall is a valuable cultural heritage of our country. Because of the old age of the city wall as well as the modern times artificial destroying, it's inner structure has changed greatly, there are some horse faces and wall body appear rifts, even happen collapse at present. This paper uses the ground penetrating radar application technology as the foundation, examines the ground penetrating radar in Shanxi Pingyao ancient city wall restoration application and its basic principles briefly. The paper further discusses the goal body examination by the ground penetrating radar, the accurate surveying results of theancient city wall interior soft soil body, holes, cracks, and so on, gives the dangerous ranking, and provides the reliable basis for the scenic spot historical site restoration.
