Abstract: Landslide is a kind of natural disaster with a high incidence,which will have a certain threat to engineering buildings and nearby residents.In the field of Landslide Exploration,highdensity electrical method has important application and high application value.The advantages of this method are high exploration accuracy,convenient operation and low cost.It has been widely used for many years.To analyze the stability of landslides by highdensity electrical method.The method is applied to the investigation of Houshan slope in Shuping Township,and on the basis of drilling verification,the thickness,sliding surface and property of the sliding body are analyzed,and then the stability of the slope under various preset working conditions is discussed by the limit equilibrium analysis method.The results of stability evaluation can provide support for the subsequent landslide treatment and response.

Key words: Landslide, Stability analysis, Geological hazard, High density electrical method
