The results show, when polar distance is bigger than the size of cross section of tunnel, the difference of anomalous feature between the corner-sections and wall-sections in tunnel is very small. The apparent resistivity is only related to the distance between section and bodies. The shielding effect of the tunnel is not so evident that the character and value of anomalous are similar with those in full space.
