Research On Landslide Stability Analysis And Governance Project Decision Making In Toudaoheâ…±landslide In ZiGui Country

Along with Three Gorges Project (TGP) reservoir storing water, landslide in this area should be governed Properly and immediately. In this paper, the Toudaoheâ…¡landslide in Zigui county is taken as an example. Multiple methods, such as prospecting, test, mechanics balance compution, numerical analysis and so on, are employed to analyze its factors of stability influence, and evaluate its stability. Further, decision making system analytical model of landslide treatment, which is based on intuitionistic fuzzy sets, is established and used to put forward governance project of the Toudaoheâ…¡landslide. Details are list as follows:(1) Characters of engineering geological condition and architectural feature of the Toudaoheâ…¡landslide in TGP are analyzed, multiple methodsare employed to obtain mechanical property of landslide and establish;(2) LEM is adopted to analyze and estimate stability of the Toudaoheâ…¡landslide. It turns out that although the landslide is in stable state in nature, but in extremely disadvantageous working condition, its stability will decrease quickly and it will slide;(3) Based on the results of LEM, the finite difference software FLAC^2d used to analyze and estimate stability of the Toudaoheâ…¡landslide. By its calculations, impacted by extremely adverse factors, the Toudaoheâ…¡landslide will slide;(4) Decision making system analytical model of landslide treatment, which is based on intuitionistic fuzzy sets, is established and used to put forward governance project of the Toudaoheâ…¡landslide in TGP.
