地质雷达探测在明镜台保护中的应用

摘要

彬县大佛寺为国家重点文物保护单位，与2014年6月被列入世界文化遗产，明镜台是大佛寺的重要组成部分。为了进一步探明明镜台基座内部空洞、裂缝、脱空等病害情况，采用地质雷达（ground penetrating radar，简称GPR）探测技术对明镜台基座进行探测，得出明镜台台基裂缝分布区带和变形沉降趋势，为明镜台的加固保护提供了详细的基础资料。%The Dafosi (Great Buddha Temple) Grottoes is a Major Historical and Cultural Site Protected at the National Level and listed as the World Cultural Heritage in June 2014. The Mingjingtai (Clear Mirror Terrace) is an important part of the Dafosi Grottoes. To further make clear the cavities, fractures, hollows and other internal diseases of the base platform of Mingjingtai, GPR (ground penetrating radar) detecting technique was applied, which revealed the fracture distribution area and the deforming and settling tendencies of the base platform of Mingjingtai and provided detailed basic data for the reinforcing conservation project of Mingjingtai.
