The landslide in southwest China has caused serious casualties and huge economic and property losses. It is very important to determine the type and scale of landslide. First, this paper introduced the principle and data processing method of high density resistivity method. Second, we summarized the different classification methods and physical characteristics of the landslide. Finally, through the comprehensive analysis of more than 20 landslide survey data obtained by high density resistivity method, it is held that the apparent resistivity characteristics of the different types of landslide are different obviously. With practical examples, this paper mainly deals with three abnormal characteristics of high density resistivity method detection, i.e., the soil landslide, rock landslide and broken rock landslide. It is proved that the high-density electrical method can deduce the type and material composition of the slope from the abnormal characteristics of the apparent resistivity, and provide guidance and demonstration for the investigation of the landslide body and the later management and drilling construction.
