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.
Abstract
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.
