Abstract: In order to reasonably arrange the subsequent archaeological excavation of ancient tombs in Xiongjiazhong, it needs to geophysically detect the location and buried depth of chamber of its main and accompany mounds. Because electrical resistivity tomography has the advantage of non-destruction, this technique is used to experimentally detect the main and accompany mounds of Xiongjiazhong ancient tomb in this paper. Two measuring lines, in which one was along NS direction and the other along EW direction, were arranged to control the main and accompany mounds, respectively, in this detection. Their locations and sizes were estimated based on the reconstructed resistivity images, which provided the basic parameters for the subsequent archaeological excavation of ancient tombs ß.
