Numerical Analysis Of Slope Stability And Its Application

High steep rock slope is a complicated systematic engineering, directly affect the stability of mine production safety and economic efficiency of enterprises.The further mining is accompanied by the increase of slope angle. In complex geological conditions, Steep open slope safety control technology is directly related to production can be, how to ensure high and steep slope stability is a important issue during the mining. This paper focuses on the research in Yunnan Xiaolongtan Buzhaoba open pit mine slope deformation mechanism, stability evaluation; using slip field theory, finite difference method, limit equilibrium method as the theoretical basis of high and steep rocky slopes and static analysis the design of safe mining, Mainly includes the following:1,through the analysis of geological data and monitoring changes in displacement, summarize Buzhaoba Mine Slope displacement trends;2,the first treatment of FLAC3D was improved using Midas/GTS software, combined with FISH language program corresponding interface program, which greatly improves the application of methods FLAC3D.3,using the finite element and finite difference software to analysis every part of the mine slope;4,application of slip coupling SLOPE/W software, calculate and analysis 346,348, N8-8 line profile stability;5,combined with structural design principles of reinforcement Belt Road, N8-8 line basis, and design calculations.
