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.
