Stability analysis of Lijiaxia landslide in Longxian County, Shaanxi Province

Lijiaxia landslide is a large rockslide,encountered in Loess Plateau which is famous for lots of loess landslides.On the basis of field geological survey,exploration of engineering geology,indoor tests of rock and soil mass,simulation calculation with Ansys software were performed on stability of Lijiaxia landslide,considering three kinds of climate conditions and three kinds of strength of slip soil.Numerical simulation shows that variation of strength of slip soil effects stability largely and Lijiaxia landslide is unstable now.The authors think it is probable to slide along main sliding belt,considering the latest deformation of Lijiaxia landslide.
