地球物理探测技术在石窟寺裂隙渗流中的应用现状及展望

Application status and prospect of geophysical detection technology in fracture seepage of grottoes

在石窟寺的保护工作中,裂缝水害对石窟文物的影响是广泛且严重的.地球物理勘探技术依据不同的岩体构造及不同的岩石物性所产生的物理场来了解岩体的裂隙特征,具有无损高效的优势,是石窟寺等岩体文物的保护工作基础.本文通过广泛调研,系统地总结了探地雷达技术、电法勘探技术、核磁共振技术等多种常用的地球物理探测手段在岩体文物裂缝探测中的相关工作,归纳了在石窟寺裂缝探测应用中存在的主要问题及解决方案.本文的研究内容不仅在石窟寺的保护研究与修复加固工作中具有重要意义,也有利于地球物理探测技术在石质相关文物保护工作中的推广与应用.

In the protection of grotto temples,the damage caused by crack water to grotto cultural relics is extensive and serious.The geophysical exploration technology can be used to explore the fracture characteristics of rock mass according to the physical field generated by different rock mass structures and different rock physical properties,which has the advantage of nondestructive and efficient,and is the basis of rock mass cultural relics protection such as grotto temples.Through widely investigation,this paper systematically summarizes the related work of many commonly used geophysical detection methods,such as ground penetrating radar technology,electrical exploration technology,nuclear magnetic resonance technology,etc.in the crack detection of rock relics,and summarizes the main problems existing in the application of the crack detection of grotto temples and their solutions.The research content of this paper is not only of great significance in the protection research,restoration and reinforcement of grotto temples,but also conducive to the popularization and application of geophysical detection technology in the protection of stone-related cultural relics.
