The invention discloses a novel method for measuring buried steel pipe corrosion rate, which comprises the following steps: (1) establishing a basic model of soil corrosion rate (the soil corrosion rate is used as the basic corrosion rate of a buried steel pipe); (2) determining influence correction factors of an alternating current overhead power transmission line according to an included angle of the alternating current overhead power transmission line and the buried steel pipe; and (3) obtaining the buried steel pipe corrosion rate according to the basic corrosion rate of the buried steel pipe and the influence correction factors of the alternating current overhead power transmission line. Through implementing the method of the invention, the pipe corrosion status in the practical work can be accurately obtained.
