摘　　要：为了得到更为准确的岩体质量评价结果,基于可拓学工程方法,在物元模型理论基础上建立工程岩体质量评价的物元模型。对待评物元的各因素特征赋予切合实际的值域,建立区间与区间的距的计算公式,应用可拓集合的关联函数,建立基于物元和关联函数的工程岩体可拓评价方法。对某矿山主要工程岩体质量进行了评价,得到岩体N1的质量等级为Ⅰ级,岩体N2、N3、N4和N5的质量等级为Ⅱ级,岩体N6的质量等级为Ⅲ级。通过与基于特征值的可拓学理论以及其他岩体质量评价方法所得到的岩体质量评价结果进行比较,验证了基于特征值域的可拓学理论在工程岩体质量评价中的可行性和可靠性。In order to obtain more accurate results of rock mass quality evaluation based on extenics engineering method,we established the matter-element model of rock quality evaluation based on the theory of matter-element model.With a review of the various factors of the matter-element of feature given practical domain, calculation formula of interval distance was established as well, and finally we applied extension set correlation functions to establish evaluation method of engineering rock mass based on the content and links function extension.Main engineering rock mass quality of the iron ore was valuated, and the results demonstrated that the rock quality level of N1 belonged to I , while N2,N3 ,N4 as well as N5 were all Ⅱ , and V6 belonged to Ⅲ.Through comparing the results of extension theory and quality evaluation of rock mass obtained by other evaluation, we verified the feasibility and reliability of engineering rock mass quality evaluation method based on feature range.
