摘要
以某露天采场为研究对象,选取层次分析和集对理论相结合的方法对该露天矿山的边坡稳定性进行系统全面的评价。首先对影响该矿山边坡的因素进行分析,得到影响较大的16个评价指标,并以此建立了该露天矿山边坡稳定性风险评价指标体系。再运用层次分析和集对理论分析相结合的方法确定各评价指标的权重值,得到边坡稳定性评价等级。通过定量分析方法对露天矿山边坡工程的稳定性进行了全面评价,能够为露天矿山边坡灾害的治理工作提供一种新的思路,从而有效预防边坡灾害。
Taking an open pit as the study object, the combined hierarchy analysis and set pair theory is se- lected to evaluate its slope stability comprehensively and systematically. Firstly, with the analysis of the factors affecting its slope stability, 16 evaluation indices of great effect are obtained and an evaluation index system of its slope stability is established. Secondly, combined the hierarchy analysis with set pair theory, the weight of each index value is determined and then the evaluation rating of slope stability is obtained. Finally, by means of quantitative analysis, the stability of the slope engineering in the open pit is evaluated comprehensively, which provides a new train of thought for the slope disaster prevention of open pits.
