Article Preview

The rock mass quality classification method was introduced for the strength parameters and deformation parameters when carrying out quantitative classification and provided a theoretical basis; Introducing unloading rock mechanics theory, the infiltration conditions of the surface, drainage measures , catchment area as well as the subsequent impact of buildings on the slope were considered in order to increase the coverage of evaluation factors; Considering finite element analysis results of three-dimensional model and reference targets selected , one kind of improved numerical analysis method based on fuzzy - accurate evaluation of slope stability was proposed. The method is based on finite element model of the calculation results and the appropriate references selected, having the calculation analysis of certain factors on the slope stability a quantitative treatment, thus objectively established the weight ratio between these factors, avoiding subjective awareness in expert scoring impacting evaluation results too large. With practical engineering analysis it shows: the method is directed against rock slope analysis , make more factors impacting rock slope stability involved in evaluation, and easy to operate.
