| Abstract: | The cathodic protection potential distribution on the exterior of tank bottom was mathematically simulated and the cathodic polarization performance was described according to the mixed polarization theory. The effects of soil resistivity and tank diameter on potential distribution of tank bottom under protection of different kinds of anode placement manners were studied and compared. The obtained results can be used in determining cathodic protection effect and choosing anode placement manner. |

| Keywords: | storage tank cathodic protection potential distribution simulation cathodic polarization performance anode placement manner |
