Abstract:Using high-density resistivity layer analysis imaging method, we detect the electrical structure of the underground medium in the geoelectric observation site of Mengcheng national geophysical observatory in Anhui. We carry out the detection by using a Wenner device and continuous rolling measurement, resulting in high-precision apparent resistivity data and electrode elevation information. Through forward and reverse calculations of the detected data, we obtain the distribution characteristics of the electrical structure of the study area in different axial directions and depths. Through the inverse calculation of the probe data, we obtain the resistivity distribution characteristics in different axial directions and at different depths, and obtain a relatively fine image of the electrical structure of the study area, which is geologically interpreted in combination with the historical probe data and drilling data. This provides a more scientific and fine background basis for the in-depth analysis and research of the resistivity observation data of Mengcheng ground.
