The invention provides a buried pipeline stray current simulation device, and relates to a long-distance pipeline corrosion test method. Treated soil is placed in the organic glass test tank, the external stray current generating electrode and the stray current counter electrode are arranged on the two sides of the interior of the organic glass test tank respectively and buried in the soil, and the waveform generator is placed outside the organic glass test tank and connected with the external stray current generating electrode and the stray current counter electrode. The heating resistance wire is arranged at the lower part of the soil, the electrochemical test piece and the corrosion test piece are buried at the bottom of the soil, the temperature sensors are arranged near the electrochemical test piece and the corrosion test piece, and the upper part of the electrochemical measurement test piece is provided with a hole for installing a reference electrode and an electrochemical test counter electrode.
