【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 weight of the evaluation index is difficult to be accurately determined in the quality evaluation of the actual engineering rock mass, the order method (TOPSIS) which approximated the ideal solution by the intuitionistic fuzzy set is applied to the quality evaluation of the engineering rock mass. The intuitionistic fuzzy set TOPSIS is introduced into the multi attribute decision making problem of the intuitionistic fuzzy set, and the intuitionistic fuzzy set is used to express the engineering rock. The weight of the evaluation index of body mass is used to reduce the difficulty of determining the weight of the index. Then, the quality evaluation of the rock mass of 10 rock masses in Xinjiang East Gobi open pit is evaluated by intuitionistic fuzzy set TOPSIS. Finally, the evaluation results are compared with the evaluation results of the RMR method, the Q method and the extenics method. The results show that the evaluation of the intuitionistic fuzzy set TOPSIS is the evaluation of the rock mass. The result is consistent with the quality of actual engineering rock mass, and is more accurate than the evaluation result of Extenics. It provides a new and reliable method for evaluating the quality of rock mass in the open pit.
