%X Multi-electrodes electrical method(MEM) is an effective tool for landslide survey,and the suitable in-situ working scheme and its data analyzing model are the base to obtain believable results. The ideal electrical models are given to figure slide-face in homogeneous soil slope,soft interlayer,and geological structure. Two dimensional apparent resistivity sections are formed with finite element method corresponding to four kinds of routine in-situ data collecting arrays,which are Wenner array,Schlumberger array,dipole-dipole array and pole-pole array. The ideal electric array and abnormal resistivity pattern are determined by analyzing the sections. An innovative data interpretation procedure for locating slide-face position in complex geological conditions is propoped,and a series of case study for slope survey with MEM are made. By analyzing the study result,it is shown that dipole-dipole array and Schlumberger array have the stronger exploration capabilities,and pole-pole array can explore the object inside wider area than other arrays with the same electrode. The apparent resistivity patterns of different types of landslide are different even if the landslide is investigated with the same electrical array. The ration parameter method can improve the capability of two dimensional apparent resistivity section to reflect the distribution of object inside landslide.
