摘　　要：针对边坡稳定性评估的复杂性和未确知性特点,在构建定性与定量指标相结合的评价体系基础上,采用G1-GRA和拉格朗日算法组合赋权思想,计算指标综合权重,建立了基于五元联系数集对分析法的边坡稳定性评价模型。应用所建立的模型对3座露天矿边坡稳定性状态进行实例分析,通过计算综合联系数,确定边坡稳定性等级,并与物元可拓和云模型评估结果进行对比。结果表明:3座露天矿边坡稳定性均为Ⅲ级,评估结果合理可靠,验证了五元联系数集对分析法在边坡稳定性评估的适用性。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 correlation 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.
