Abstract: Linjiaya landslide is a landslide system with double sliding bodies. This paper deals with its characteristics and the factors controlling its deformation and analyses its deformation mechanism. General Sarma method and new Sarma method, which considers the sliding effect of upper sliding body, are used in analysis of Linjiaya landslide stability. It is shown that the sliding effect of upper sliding body should be considered, so that the calculation result is more effective in design of controlling landslide.
