Evaluation of Slope Stability Based on Five-element Correlation Set Analysis Method
In view of the complexity and uncertainty of slope stability evaluation,an evaluation system combining qualitative and quantitative indexes is constructed,and the comprehensive weights of indexes are calculated by using G1-GRA and Lagrange algorithm,and a slope stability evaluation model is established based on the analysis of five-element correlation sets.The model is used to analyze the slope stability state of three open-pit mines,and the slope stability grade is determined by calculating the comprehensive corre-lation number,and compared with the evaluation results of matter-element extension and cloud model.The results show that the slope stability of the three open-pit mines is Level III,and the evaluation results are reasonable and reliable,which verifies the applicability of the five-element correlation number set analysis method in slope stability evaluation.
