    FORMATION MECHANISM OF LIUJIAPO LANDSLIDE IN LANGAO COUNTY, SOUTHERN SHAANXI PROVINCE

    • Liujiapo landslide is located at the northern Langao County of Shanxi Province. It is a landslide of loose deposits type. The slide is consisted of clayey gravelly sand with low permeability. The sand is easy to occur seepage deformation under the dynamic hydraulic pressure. Mud-slate and schist with shallow weathering depth constitutes the bedrock under the landslide. So the difference in the engineering properties between the sliding mass and the sliding bed is evident. . The interface is the main slip face of the landslide. The landslide is an old that had occurred to deformation and slide many times. Removement of the landslide resulted from influence factors such as continual strong rainfall and cut slope so on in 2003. The landslide is unsteady at present. If it encounters strong rainfall, it will occur to lose its integer stability. The survey for regional landslide shows that Liujiapo landslide can be a representative in southern Qinling in terms of landslide type or substance composition and deformation rule.
