Potential distributions of deep well anodic electric field on external tank bottom were derived according to the basic law of electromagnetic field and the geometry characteristics of cathodic protection system.Making use of electric field superposition principle,considering the action of anodic and cathodic electric fields,the potential distributions on external tank bottom under the protection of deep well anode were studied.The calculated results were compared and agred well with the measured data.
