| Abstract: |
| By means of natural burying cables and their materials in soda soil in Daqing site and periodically testing soil environmental factors and soil microbes, the rules and causes of corrosion were studied. The result indicated that after 12 years’ burying all the cables’plastic jackets keep their performance well; Pb has a medium corrosion level; painted steel band is corroded seriously; and Al perforates. High pH level above 10, low soil conductance, and large amount of microbes in soda soil are the main causes of corrosion. |
