The Application of Two-dimensional Electrical Sounding Finite Element Method Forward Modeling in Groundwater Exploration

Abstract

Electromethod exploration is an important means of detecting groundwater. Based on the finite unit method, this paper establishes
models of sandstone, karst and paleochannel water-bearing structures, and compares and analyzes the detection effects of triple-pole, Wenner
alpha and dipole devices. The results show that: the triple-pole device is suitable for shallow exploration; the Wenner ? device has clear imaging of deep structures; the dipole device has high vertical resolution but more false anomalies. The measured data verified the reliability of the
orthogonal method and provided theoretical support for the selection of groundwater exploration devices.
