| 摘 要： | 将线缆制品及其材料自然埋藏于大庆苏打盐土中,周期性测量土壤环境的相关数据,研究试件腐蚀变化规律及原因。结果表明,各种线缆外护套的性能没有明显劣化;铅的腐蚀程度为中等,涂漆钢带的腐蚀程度较重,铝的腐蚀程度严重(发生穿孔)。金属严重腐蚀的主要原因是苏打盐土的pH值高达10,以及电阻率很低、土壤微生物含量较高。

| 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 A1 perforates. High pH level above 10, low soil conductance, and large amount of microbes in soda soil are the main causes of corrosion. |
