Abstract
Taking landslide with accumulation layer-bedrock contact surface which located in Langao county in Shaanxi province as the research object, the basic characters of landslides are summarized by field investigating, engineering geological analyzing and mathematical statistics method, the main characters can be concluded as follows:(1)those landslides mainly distribute in 600 m~ 1200 m elevation, slope forms are mainly convex with 180~ 270 ø dips and 20~40 ø gradient, meanwhile, those landslides distribute along the tectonic zone; (2) this kind of landslide is always shallow landslide, their property are mainly composed by crushed silty clay or gravel soil, The sliding form is mainly arc and line, which is easy to form "debris flow" during the sliding process;(3) the main failure mode are creep-rupture and slip-push. This research has guiding significance to reveal the formation mechanism and disaster prevention of landslide with accumulation layer-bedrock contact surface.
