摘　　要：在石窟寺保护中,对石窟岩体裂隙渗流网络的精细探测是实施石窟寺渗水病害防护的基础,地球物理探测技术可以无损或微损的方式对石窟岩体的裂隙渗流网络进行探测。本研究首先对石窟岩体裂隙渗流网络的多种地球物理响应机理进行了剖析;其次提出了石窟岩体裂隙渗流网络高精度探测的高密度电法地—井—崖差分探测技术,利用裂隙周边渗水区产生的电阻率变化的体积效应进行探测。采用所提出的方法在重庆大足石刻北山试验场进行实验,对微小的渗水裂隙进行了高精度探测,验证了所提出技术的有效性。研究结果为石窟岩体裂隙渗流网络的探测提供了新的高精度方法。In the conservation of cave temples,the precise detection of fracture seepage networks in sandstone rock surfaces is the basis for implementing effective prevention and control measures.Modern geophysical exploration technology is capable of conducting non-destructive investigations to detect micro-damage in various types of rock formations.This research utilizes this technology to detect and measure multiple geophysical response mechanisms in the fracture seepage networks of sandstone temples,and follows by proposing the further use of a high-density electrical method known as the ground-well-cliff differential detection technique for additional investigation of fractures and seepage.This technique utilizes the volumetric effect of resistivity changes generated by the seepage zones around fractures in rock formations.This method has previously been applied to the precise detection of tiny seepage fractures in the Dazu Rock Carvings at an experimental site at Beishan,which verifies the effectiveness of the method.
