摘要:
为提高边坡稳定性评价结果的准确性，应用TOPSIS法，并将垂面距离代替欧氏距离的正交投影法与之结合，采用变异系数法确定指标客观权重，提出一种改进的TOPSIS-CV法。从边坡几何参数、岩体强度参数及外部情况等3个方面综合考虑影响边坡稳定性的7个评价指标，建立边坡稳定性的评价指标体系，将改进的TOPSIS-CV模型应用于某露天矿边坡的稳定性综合评价中。研究结果表明：采用垂面距离代替欧氏距离，贴近度更加容易区分，边坡稳定性评价结果准确率达90 %；与传统的TOPSIS法相比，改进的TOPSIS-CV法计算结果更为精确，更加容易对边坡稳定性进行综合评判；改进的TOPSIS-CV法具有良好的工程应用价值。

Abstract:
In order to improve the accuracy of the slope stability evaluation results,the TOPSIS method is applied combined with the orthogonal projection method with Euclidean distance replaced by vertical distance,the variation coefficient method is used to determine the objective weight of the index,and an improved TOPSIS-CV method is proposed.7 evaluation indexes affecting slope stability are comprehensively considered from 3 aspects:slope geometric parameters,rock mass strength parameters and external conditions,the slope stability evaluation index system is established,and the improved TOPSIS-CV model is applied to the comprehensive evaluation of slope stability of an open-pit mine.The research results show that using the vertical distance instead of the Euclidean distance,the paste progress is easier to distinguish,and the accuracy of the slope stability evaluation results is 90 %,compared with the traditional TOPSIS method,the improved TOPSIS-CV method is more accurate and can more easily comprehensively evaluate the slope stability,the improved TOPSIS-CV method has good engineering application value.
