Comparative Study on 3D High-Density Electrical Method in Fine Near-surface Detection
In order to achieve fine detection of underground structures in engineering sites,a comparative study of three-dimensional high-density electrical fine detection of three commonly used types of quadrupole devices(Werner,Schlumberger,Dipole)in engineering surveys was conducted in the research area.We mainly conducted comparative analysis on the three-dimensional inversion visualization results of various devices and the slicing results in different directions.The research results indicate that all three devices can achieve precise characterization of shallow geological bodies,but there are certain differences in data coverage,detection depth,resolution,and other aspects.Based on the analysis results,a selection scheme for the type of 3D high-density electrical field data acquisition device for engineering site exploration has been proposed,which has certain reference and guiding significance for the practical application of 3D high-density electrical engineering in the future.
