微电极测深系统在石质文物表层劣化检测中的应用研究

Micro-electrode system development and applied research in the deterioration detection of the surface of stone monument

本文主要介绍了为检测石质文物表层劣化程度而研制开发的微电极高密度电阻率测深成像系统的指标参数及电阻率精细成像的基本原理,并结合物理模型试验结果,在云冈石窟对文物近表面的微构造、风化带、含水程度进行了精细成像测试,测试结果表明,该系统能有效地评价文物近表面的微构造、风化带划分以及含水情况,说明其在文物保护及监测领域具有较高的推广应用价值。

This paper introduces micro-electrode high-density resistivity imaging fine principle, the development of test instruments and the survey of the field of heritage conservation applications combined with the physical model test results.The Yungang Grottoes in the heritage of the micro-structure near- surface,weathering zone,the extent of the water-bearing fine imaging test results show that the system can effectively evaluate the artifacts near the surface of micro-structure,weathering zone boundaries and the aquifer,the investigation with the promotion of heritage value.
