Abstract In this study, the high density resistivity imaging method was used to detect the electrical structure in the southern segment of Baobi fault, which lies geographically from Yuhekou to Fangzhuang. As a result, some obvious resistivity discontinuities were revealed below the survey lines. With the aid of surface geological cognition, the authors infer that one of the discontinuities corresponds to Bobi fault. Furthermore, the authors discussed the segmentation of the Bobi fault by combining the previous results of geology and geophysics. The authors consider that Yuhekou is the boundary point.
