Abstract
Taking the Gaozhi Village landslide as an example, this paper discussed the application of FLAC3D in landslide stability analysis and evaluation. The author ifrst introduced the basic principle and main process of FLAC3D, and then simulated the Gaozhi Village landslide stability under natural state and heavy rain state by Mohr-Coulomb of FLAC3D. The simulation result intuitively showed the distribution characteristics of plastic deformation and horizontal displacement of the slope in the above two conditions, and clearly showed the potential sliding surface inside the slope. According to the result of numerical simulation, the article analyzed and evaluated the landslide stability, studied and discussed the deformation and failure forms of the landslide. By analyzing the plastic deformation and displacement of slope, the author considered that the landslide is basically stable under the natural state and is unstable and likely to slide and lose its stability in the local area under the continuous high intensity rainfall state. This is consistent with the investigation and analysis. This result shows it is feasible and more simple and more intuitive and convenient to analyze and evaluate the stability of landslide by FLAC3D. Compared with the traditional limit equilibrium method, FLAC3D has the incomparable advantage.关键词
