Li. Freiman, Calculating the vertical anodes of the cathodic protection systems for structures buried in multilayer soils, PROT MET R, 35(2), 1999, pp. 185-190
Usable methods for computating the vertical groundings of cathodic protecti
on systems in stratified soils are compared, and a way of the refined recko
ning of grounding resistance to current spreading is outlined.
