Slope Stability Evaluation Based on GIS and Numerical Simulation

There are two main research directions in the field of slope stability evaluation. One is slope stability qualitative evaluation and zoning based on GIS, the other is single slope stability quantitive evaluation based on limit equilibrium method or numerical simulation method. The combination points of the present two research directions are summarized. The functions such as profile automatic generation and preprocessing of FLAC-2D simulation data are realized based on integrating of ArcGIS and FLAC-2D by program developing technique. A case study of certain project is presented to test the reliability of the model, including slope stability qualitative and quantitive evaluations. The result is objective and accurate.
