The invention discloses a method for acquiring polarization potential of a buried pipeline. The method comprises the following steps that cathode protection data of each section along the pipeline aremanually collected; a prediction model of the polarization potential, relative to current, electrifying potential and soil resistivity, of the pipeline is established by using a BP neural network principle; an intelligent test pile collects the cathode protection data of each section along the pipeline and transmits the data to a data server; and a processor calls the cathode protection data in the data server, and a polarization potential value is acquired by using the prediction model, relative to the current, the electrifying potential and the soil resistivity, of the polarization potential. According to the method, the data can be automatically collected through the intelligent test pile and transmitted to the data server, after the data in the data server are imported into the processor, the polarization pot
