In order to determinethe geophysical characteristics and physicalstate of the ancient city walls, which areunder different conditions, and to exploretheeffectiveness ofan integrated method to visualizeancient city walls, A survey using a variety of methods was conducted. It included, primarily, electric resistivity tomography (ERT),magnetometry (MAG), ground penetrating radar (GPR) and γrayspectrometry. Combining thesegeophysical method results with 2D and 3D data processing and display technology, the location and the geophysical characteristics of the ancientcitywalls were successfully detected. To reduce ambiguity in interpretation, approaches to integrating multidimensional geophysical data were also examined. Finally, the geophysical models of the different walls were summarized, and optimal combination methods for further study were proposed. These includeERT and GPR for the west wall, MAG and ERTfor the southeast wall and ERT and GPR for the north wall.The results show that application ofintegrated geophysical methodsis the preferred technology for the archaeological exploration of the ancient city walls.
