Using resistivity as index and referring to the law about effect of slope to resistivity, the apparent resistivities of geophysical model concerned with unsteady rock type slope failure were calculated systematically by using the boundary integral equation method. After studying the feature of resistivity response of slope failure, the variety of resistivity during evolution of slope from steady to unsteady was found and the characteristics of resistivity response about slope failure was concluded. These make electrical exploring method for detecting the slip plane or structural plane of slope...
