Abstract: Identification of landslidingsurface is the crucial problem of landslide investigation and research. It is also important for landslide stability and construction design. The basic type of landslidingsurface is categorized to rock surface,sediment surface,and soil surface. The geological characters of landslidingsurface can be classified as smooth friction surface,striation,mudding zone and diamond shearing wedge with directional range. Based on this classification,it is generated that the main methods for landslidingsurface identification contains mechanical analysis,field geology judgment,site exploration,displacement monitoring and geophysical detection. Applicability of these methods is also discussed in the paper．
