地球物理探测技术在大足石刻保护中的应用
|
摘要
由于长时间自然因素和人为因素的影响,大足石刻产生了严重的地质病害。将高密度电阻率法、电磁波CT技术、钻孔电视技术和探地雷达等地球物理探测技术应用在大足石刻保护工程中。通过上述物探手段,查明了测区内主要控水构造或裂隙的平面分布规律、地下含水带的空间分布格局、第四系覆盖层的分布以及岩画赋存岩体的结构特征等,取得了理想的效果,为大足石刻保护提供了依据。
On account of the influence of natural and man-made factor,there have been serious geological diseases in Dazu Rock Carvings.The paper expounded the application of geophysical technologies in the conservation of Dazu Rock Carvings,including high-density resistivity method,electromagnetic wave computerized tomography(CT) technology,borehole television technology and geological radar technology,and so on.The plane distribution rule of the main water bearing structures,the spatial distribution pattern of the aquifer,the distribution of the Quaternary overburden and the structural characteristics of rock masses which the rock paintings occurreto was ascertained through the methods mentioned above.A ideal results is achieved and provides the basis for the conservation of Dazu Rock Carvings.
