摘　　要：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。Traditional ＂deterministic＂ research methods have some limits in the slope stability evaluation of gangue dump. In or- der to evaluate the slope stability of gangue dump more scientifically and reasonably, the AI-IP structure model was established on the basis of summarizing the existing study results of slope stability. Then, AHP was used to determine the weights of the influence factors and a semi-trapezoid membership function was selected to determine membership. Multi-level fuzzy mathemat- ics comprehensive assessment method was used to evaluate the slope stability of gangue dump, and the evaluation results were obtained. This evaluation model was applied to Tunlan gangue dump to verify its reliability in engineering practice. The results indicated that using this model could make the evaluation work of slope stability of gangue dump more comprehensive as well as the evaluation results and engineering practices were well-matched. Therefore this evaluation method was simple and possessed a high confidence level which could offer a favorable reference for similar evaluation works in the future.
