在矸石山边坡稳定性的评价方面,传统的“确定型”的研究方法具有一定的局限性。为更科学合理的对矸石山边坡稳定性进行评价,在总结现有边坡稳定性研究成果的基础上,建立了矸石山边坡稳定性层次分析结构模型,以层次分析法确定影响因素的权重,选择“岭形”隶属函数确定隶属度,采用多层次模糊数学综合评价的方法对其稳定性进行评价,最终给出评价结果。将该评价模型应用于屯兰矿矸石山的稳定性评价中,对模型的准确性加以工程验证。研究结果显示,使用此模型可以更全面的评价矸石山边坡的稳定性,评价结果与工程实际十分吻合。本评价方法简单,可信度高,可以为今后类似的评价工作提供良好的参考。
In the evaluation of slope stability of waste rock slope, the traditional “deterministic” research method has some limitations. In order to evaluate the slope stability of gangue slope more scientific and reasonable, on the basis of summarizing the research results of existing slope stability, the hierarchical structure analysis model of gangue slope stability was established, and the influential factors were determined by analytic hierarchy process Weight, select “ridge shape ” membership function to determine the degree of membership, using multi-level fuzzy mathematics comprehensive evaluation method to evaluate its stability, and finally give the evaluation results. The evaluation model was applied to the stability evaluation of gangue hill in Tunlan, and the accuracy of the model was verified by engineering. The results show that using this model can evaluate the stability of gangue slope more completely, and the evaluation results are in good agreement with engineering practice. This evaluation method is simple and credible, which can provide a good reference for similar evaluation in the future.
