Abstract:: On the basis of detailed investigation and geological survey on large landslide at the edge of loess tableland lying on the north of Weihe River in Baoji City, some conclusions could be drawn by discussing several factors including topography, lithology, geological structure, groundwater and human activities, etc. First of all, neotectonic movements create 100 m to 200 m high, 25°to 45° steep and gibbous slopes on the edge of loess tableland which is an advantage topographic environment for landslide occurrence. Secondly, controlling factors of landslide in the area are special kinds of lithologic association, loess—terrain—red clay of Sanmen group and loess—Hipparion laterite—bedrock respectively involving soft intercalations which are Sanmen group red clay and Hipparion laterite, and anisotropy due to small-scale faults and joints in slopes. Thirdly, underground water and human activities are the main triggers to large loess landslides at present. Based on the obtained results, identification elements including topographic characteristics, failure modes and dynamic effect are determined.
