Complex topography seriously affects the interpretation of CSAMT. Considering the influence of the topography, the authors analyzed in detail the geoelectric section model and made CSAMT two-dimensional inversion for the direct calculation data of the model. The result is basically consistent with the shape of the direct model. The electric section obtained can satisfactorily reflect the underground geological structure and accord with the geological data. All this proves the correctness and effectiveness of this technique.
