Detection method for boulders in subway shield zones based on data fusion multi-resistivity three-dimensional tomography

Identification of the Hydrogeological Potential in Langos-San Andres, by Means of Electrical Resistivity Tomography Interpretation

“…4.07 software (licensed from the National University of Chimborazo) to perform the inversion in two dimensions, which is based on a smoothed least squares sequence with damping; the same sequence was refined with a trial-and-error comparison (Figure 2), using the finite difference method or the finite element method. From the data obtained in the inversion of the Res2dinv software, all the electrical topographies were projected in three dimensions using the Res3D software 3.13.50 (National University of Chimborazo license), which performs an inverse three-dimensional visualization of the resistivity data of the lithological materials that exist in the subsoil [18].…”
