摘要

摘要: 2D高密度电法在古墓葬勘探中应用较多，但二维剖面解释局限性愈发突出。以2D平行或等角度放射状测线为基础的拟3D高密度电法能够一定程度上给出三维信息，但对地表条件要求较高，灵活性稍差。3D高密度电法能够给出详细的3D探测信息，但施工效率偏低，且难以适应复杂地表环境。为解决复杂地表环境古墓葬探测问题，提出了一种多方位拟3D高密度电法技术，并在一个位于密集竹林中的大型古墓葬调查中进行了应用研究。结合地表条件布设多个方位的2D高密度电法测线，将多个方位的2D反演数据合并为拟3D数据体，进行可视化解释获得了内部结构的3D信息。结果表明，该技术能够适应复杂环境，拟三维数据不仅能补充二维解释缺失的信息，且与钻探结果基本吻合。

Abstract: 2D electrical resistivity tomography is widely used in the exploration of ancient tombs, but the limitations of two-dimensional section interpretation are more and more prominent. The pseudo-3D electrical resistivity tomography based on 2D parallel or equi-angled radial lines can give three-dimensional information to a certain extent, but the requirements for surface conditions are higher and the flexibility is slightly worse.Detailed 3D information can be given by 3D electrical resistivity tomography, but the acquisition efficiency is low and it is difficult to adapt to complex surface environments. In order to solve the problem of detecting ancient mausoleums under complicated surface, a multi-azimuth pseudo-3D electrical resistivity tomography was proposed, which was applied in the detection of large ancient mausoleums in an intensive bamboo forest.According to the actual situation of the surface, 2D lines of multiple orientations can be laid out, and 2D inversion data of all orientations are merged into a pseudo 3D data volume, and 3D internal structure information is obtained by visual interpretation. The results show that the technology can adapt to the complex environment, and the pseudo-3D data can not only supplement the 2D interpretation of missing information, but also basically coincide with the drilling results.
