Abstract: Landslide is a major issue endangers personal safety. Detecting distribution of landslide-face is a key factor in controlling landslide. And electrical resistivity tomography (ERT) method is sensitive to interface of different layers, which is used to detect landslide-face. Firstly, four common landslide models are simplified basing on existing landside models. Secondly, systematic numerical simulation is carried out by finite element method about different types of landslides. Response characteristics of landslide-face are obtained using ERT method. Rapid identification of different types of landslide-face is put forward. Then, inversion about different types of landslide-face is done using damping least squares inversion method. Inversion imaging discipline of landslide-face is summarized using ERT. Combined with response characteristics of numerical simulation, anomaly identification features are put forward. At last, ERT method is used to detect landslide in Xili town, Yiyuan city of Shandong province. Distribution of landslide-face is reflected clearly, which shows that ERT method is efficient in detecting landslide-face. And it is laying a solid foundation for conceptual design of landslide controlling
