微电极高密度电法探测在文物保护中的应用研究

THE RESEARCH ABOUT THE APPLICATION OF RELIC PROTECTION WITH THE METHOD OF MICROELECTRODE DETECTION OF HIGHDENSITY ELECTRICAL

高密度电法探测是一种分辨率较高的物探方法,这里结合石质文物表层劣化程度检测及石窟渗水构造探测研究,介绍了微电极高密度电法探测系统的精细成像原理及物理模型试验结果。在山西云冈石窟文物近表层和洛阳龙门石窟潜溪寺地表,进行了微电极高密度电法探测。经测试结果表明,微电极高密度电法探测系统,能有效地评价文物近表面微构造(裂隙)发育、含水情况和划分风化带,说明微电极高密度电法探测系统在文物监测、保护领域能发挥重要的作用。

Detection of high-density electrical is a geophysical method of higher resolution.This paper which combines the detection of the deteriorate level of stone relic's surface layer with the research of constructional survey in grotto introduces the principle of meticulous imaging and experimental result of the physical model based on the system of microelectrode detection of highdensity electrical.The test result which is obtained from the survey of microelectrode detection of high-density electrical at near-surface of Yungang grotto in Shanxi province and surface of the QianXi temple in Longmen grotto shows that the system of microelectrode(crack) detection of high-density electrical is able to effectively evaluate the micro-structure development of the relic's surface layer and watery situation,divide weathered zone,and the result prove that this system is able to play an important role in the area of relic monitoring and protecting.
