摘 要: 为了解决实际工程岩体质量评价时评价指标权重难以准确确定的问题,提出将直觉模糊集逼近于理想解的排序法(TOPSIS)用于工程岩体质量评价。直觉模糊集TOPSIS是将TOPSIS引入直觉模糊集多属性决策问题中,利用直觉模糊集表示工程岩体质量的评价指标权重,降低确定指标权重的难度;然后,采用直觉模糊集TOPSIS对新疆东戈壁露天矿的10处岩体进行工程岩体质量评价;最后,将评价结果与RMR法、Q法和可拓学法的评价结果进行比较。研究结果表明:直觉模糊集TOPSIS的评价结果与实际工程岩体质量相吻合,并且比可拓学的评价结果更准确,为露天矿工程岩体质量的评价提供了一种新的可靠方法。

Abstract:In order to solve the problem that the evaluation index weight is difficult to determine accurately in the actual engineering rock mass evaluation, intuitionistic fuzzy set TOPSIS for engineering rock mass evaluation was presented. Intuitionistic fuzzy sets TOPSIS introduced TOPSIS into intuitionistic fuzzy set multi-attribute decision making problem. Firstly, use intuitionistic fuzzy set to represent the weight of evaluations of engineering rock mass quality, and it greatly reduces the difficulty of determining the index weight. Then 10 engineering rock samples was evaluated by intuitionistic fuzzy set TOPSIS in Dong Gebi open-pit mine, and the evaluation results were compared with the RMR method, Q method and extenics method. The results show that the evaluation results of the intuitionistic fuzzy set TOPSIS are consistent with the practical engineering rock mass, and more accurate than the extenics evaluation results. It provides a new reliable method for the evaluation of rock mass of open-pit mine.

 

Key words: rock mass quality; intuitionistic fuzzy set; technique for order preference by similarity to an ideal solution; index weight; open-pit mine
