Stability Analysis And Evaluation Research On Baotaliang Landslide In Zhenping County

Landslide is a major multiple geographical hazard,which does a great damage.It not onlydamages human’s life,but also does destructiveness to people’s prooerty、environment andresources.So it is emergency to enhance the study of landslide stability and work ofprevention and cure.Taking the Baotaliang landslide in Zhenping as study object,on the basis of fullystudying the topography,lithology,geological structure,hydro-geological conditions andmeteorological characteristics in this area and through on-site survey,indoor and outdoorexperiments,make a detailed analysis for the shape features, material features,geotechnicalparameters and the Fos of the Baotaliang landslide.On the base of analyzing the stabilityfactors,this article considers that water is the most important stable factor and humanengineering activities are also very important for the stability of the Baotalianglandslide.Engineering geology analysis and limit equilibrium method and numerical analysisare combined to evaluate the current steady-state of the landslide qualitatively andquantitatively.The recombination numerical simulation method FLAC3D,estalish a geologicalmodel to simulate the landslide stability.Then comprehensive anlysis the theoretical resultsand simulation results of stability of Baotaliang landslide. According to the conclusions of thelandslide stability,analysis the control program of the landslide,determine that the stabilityof Baotaliang landslide is poor.Three corresponding landslide control program have been brought forward by integratingthe characteristics of the landslide and its evaluation findings of stability.After the election,itis recommended to use a comprehensive program,mainly concrete frame with prestressedcable lattice projects and drainage works,supplemented by partial side cut,slope protectionworks,concrete frame with anchor lattice and landslide deformation monitoring. The conclusions will have a certain reference value not only to Baotaliang landslideprevention,but also to landslide disaster management for the similar region.
