中文摘要：
用土壤电位梯度法和管地电位连续监测法,研究了高压线路对地下输油管道中杂散电流的影响规律.结果表明,当管线与高压线平行或交叉时,管道中存在较强的杂散电流;且随与离高压线距离的减小而增强;在杂散电流的作用下,管道会加速腐蚀.建议在杂散电流较强的管段采取排流保护措施.
英文摘要：
Nearby the places where pipelines were buried there always exist high-voltage electric transmitting lines, and therefore, from the pipelines stray current may intensively be released and run into the ground. When high-voltage lines are parallel to or over-crossing pipelines, there should be a strong stray current in the pipelines, and as the distance of high-voltage line to pipelines becoms shorter, the stray current becomes stronger. Under the effects of stray current, the corrosion of pipelines is being accelerated. In order to prevent the pipline from corrosion induced by stray current, methods of current drainage should be put into effect in such areas.
