Fengjie County Outang Landslide Stability Analysis And Monitoring Governance Program

Landslide is one of the world’s three major geological disasters, mainly in themountainous and hilly areas. With the vigorous development of China’s waterconservancy construction of water alone, especially the construction of the ThreeGorges Project. Due to the frequent natural factors and human activities，lead toendless reservoir of various landslide. This paper describes the regional geologyFengjie County Outang landslide area geology article introduces the basic geographyof Fengjie County Outang basic geography landslide case. Basic access to relevantinformation and reports on the pre-survey,come Outang landslide characteristics andformation conditions. Using Seep/W dimensional Geo-Studio-dimensional numericalfinite element simulation software seepage analysis module, Slope/W stabilityanalysis module, set of natural conditions and a variety of water level, rainfallconditions to simulate the flow field landslide,import slope stability analysis moduleby seepage field model, the flow curves obtained landslide stability. On the basis ofthe two-dimensional numerical simulation software to analyze the results, as a basisfor that, use Flac3D dimensional finite difference numerical simulation software tosimulate the landslide landslide stress in natural conditions, storm water conditions aswell as the limits of the conditions and strain, according to the simulation results ofthe analysis of landslide vertical stress, combined displacement, shear strainincrement, pore water pressure distribution and slip direction displacement contoursto determine the stability of the landslide, the results of two-dimensional numericalsimulation software and fitting results are consistent. By two-dimensional,three-dimensional numerical simulation results analysis software, draw Outanglandslide multiple areas in an unstable state, based on the results of the monitoringprogram proposed, conduct a real-time monitoring of landslide, using surfacedisplacement monitoring, water monitoring, surveillance and other monitoring toolscrack and expect the data to prove by monitoring the results of numerical simulationsoftware. According to the monitoring results further confirm each and numericalsimulation results, proposed a landslide control program suggested by comparison ofthe various governance programs, including governance means setting the selected pile, bank protection works, drainage works and other means, through these means toprevent the occurrence of landslide hazards, to ensure security and safety of theresidents of the landslide on the shipping, property...
