面波勘探在某古城墙无损检测中的应用

Application of Surface Wave Exploration in an Ancient Wall Non-destructive Testing

该文介绍了面波的基本原理,详细分析了开展面波检测的地球物理前提,以正常墙体与存在隐患的墙体为对比,研究了墙体裂隙、局部脱空、土体不均常见缺陷的面波色谱图像特征及异常识别特征,为古墙体无损检测提供了一定的借鉴。

In this paper, the basic principle of surface wave is introduced, and the geophysical premise of surface wave detection is analyzed in detail. Based on the comparison between the normal wall and the wall with hidden dangers, the characteristics of surface wave chromatogram image and anomaly identification of the common defects such as wall cracks, local void and soil uneven are studied, which provides a certain reference for non-destructive testing of ancient wall.
