Stability Analysis Of Pebbly Clay Landslide In Wangjiadong Of Sichuan

This paper carried out extensive and in-depth research on stability analysis aboutslope, Combined with WangJiaDong landslide monitoring treatment project inPengshui County, mainly studies three-dimensional numerical simulation and analysismethod about bedding limestone additional weak interlayer of landslide in southeastChongqing, and on this basis proposed governance programs. Mainly be summarizedas follows:①This paper discusses the current widespread adoption of landslide stabilityanalysis method,including the rigid body limit equilibrium method, fuzzy mathematicsmethod, discrete element method, artificial neural network and finite element method(fem). Summarizes the basic principles of each method and stability analysis of solvingsteps, and points out the method of adaptive scope and shortcomings.②Combined with wang family of cohesive soil containing stone slide monitoring,field survey and the deformation and failure process of a stone the size of the cohesivesoil landslide, influence factors, formation mechanism and basic deformation andfailure characteristics of the analysis and research of the system.③By Wang Jia Dong cohesive soil landslide regional engineering geologicalconditions, properties of research, to analyze the landslide causes and reasonableselection, and value, using the rigid body limit equilibrium method and elastic-plasticstrength subtraction based on the Ansys analysis of landslide stability, through thecontrast analysis results: township stone NaJiangXian unity cohesive soil landslidealong the rock and soil interface as a whole in a stable state, but the front right front toslope landslide slope shoulder strong deformation zone in the heavy rain saturatedcondition is in stable condition, further deformation to the unstable~arc failuredevelopment, main endanger the unity township roads, power station diversionchannels and the villagers on the life and property security. Given its size, if furtherwork will be difficult to change after a landslide governance, in order to prevent thefurther expansion of geological hazard, the front slope to the slope shoulder the strongdeformation of landslide area is necessary to take some engineering measures tostrengthen.④Based on the research of the engineering geological conditions, properties ofnorth area of WangJiaDong landslide, through analysis of the causes and makereasonable selection on constitutive parameters, using rigid body limit equilibriummethod and...
