输电线路与地下油气管线平行、交叉的情况大量存在。分析了输电线路对地下油气管线的静电感应、磁感应和地电位升，结合相关规程要求，得出了输电线路在油气管线上感应电压的计算公式，并计算了某1 000 kV 输电线路对地下油气管线的感应电压，所得结果可为输电线路跨越地下油气管线设计提供参考。

It frequently happens that the power transmission lines are parallel to or cross over the buried oil/gas pipelines. This paper analyzed the electrostatic induction, magnetic induction and ground potential of transmission lines and buried oil/gas pipelines; and obtained a computational formula for induced voltage of power lines on oil/gas pipelines. On this basis, the induced voltage of 1 000 kV power transmission lines on the buried oil/gas pipelines was calculated, which provided reference for design of transmission lines cross over buried oil/ gas pipelines.
