The invention discloses a finite element-based grounding electrode overflow characteristic analysis method under different soil models. The method comprises the following steps of using finite element software for modeling calculation by comprising steps of constructing a geodetic soil geometry model; constructing a grounding electrode geometry and forming a combined body model; respectively adding materials to the soil and the grounding electrode geometry, and applying different conductivities and relative dielectric constants; applying initial and boundary conditions such as current conservation, electric insulation, grounding, a current initial value and a current terminal to a corresponding region of the model; selecting a related reference line and a reference surface on the model so as to observe voltage and current results; carrying out mesh generation on the model, and solving a finite element; obtaining a current and voltage calculation result on the selected reference line and reference surface; cha
