Application of Two-Dimensional Electrical Resistivity Tomography in Mapping Engineering Geological Structure of Shaying River Basin
The geological structure of Shaying River Basin is complex, and the lithology of the study area includes alluvium, volcanic ash and granite. Geological contacts, faults and fault zones found in the study area can indicate the geological evolution of the area. In order to study these important geological features, two-dimensional electrical resistivity tomography has been further developed and studied. The method can paint subsurface images of geological structures. This paper studies the survey of three independent survey lines of different lengths. A dipole array and 10m electrode spacing are used to investigate. The purpose of this paper is to determine the subsurface geological contact and determine whether there is a fault or fault zone at the contact zone. The inversion results of two-dimensional electrical resistivity tomography have successfully characterized the types of faults, contact surfaces, fractures and other geological structures. The results show that the two-dimensional electrical resistivity tomography method can be used to map the geological lineages of Shaying River Basin.
