摘　　要：无损监测古建筑内部结构特征是进行文物保护的关键。为确定临海市古长城结构和墙体内部缺陷,本研究利用100 MHz和270 MHz天线组合的探地雷达对长城不同方位上墙体结构进行了无损检测。检测结果表明临海市古长城墙体结构分层情况明显,通过探地雷达信号反射图像发现,墙体内部缺陷反应清晰,存在内部疏松、缝隙、脱空等内部病害隐患。研究表明探地雷达方法在此类古城墙结构和缺陷检测中结果可靠,研究结果可为古长城结构保护提供技术支持。Non-destructive testing of the internal structural characteristics of ancient buildings is the key to preserving cultural relics.To determine the structures and internal defects of the ancient Great Wall in Linhai City,this study performed non-destructive testing of the wall structures in different orientations using a ground-penetrating radar(GPR)combining 100 MHz and 270 MHz antennas.The testing results show significant structural stratification in the ancient Great Wall.The GPR signal-reflected images reveal clear internal wall defects like pores,cracks,voids,and other hidden dangers.This study demonstrates the reliability of the GPR in detecting structures and defects of ancient walls,there by providing technical support for the structural protection of the ancient Great Wall.
