摘要
针对传统岩体质量评价方法的局限性与不足,以模糊数学为理论基础,结合层次分析法,建立了深部岩体质量的二级模糊综合评价模型。在全面分析岩体质量的影响因素后,综合选取了14个评价指标,并按照指标的层次性进行划分,同时选用正态型函数作为隶属函数,运用二级评判的方法确定评价指标的权重,对深部岩体进行评价。从而克服传统评价方法的缺陷,使结果更加合理。最后,以三山岛金矿为例,运用该模型对-555m水平的岩体进行评价分析,得出岩体质量为Ⅲ类岩体的结论,与矿山实际情况相符,验证了该方法的正确性与合理性。
Aiming at deficiencies in traditional evaluation methods for rock mass quality,on the basis of fuzzy mathematics theory and combining with Analytic Hierarchy Process,the model of two-stage fuzzy comprehensive evaluation was established to classify the deep rock quality.After comprehensively analysis on influential indexes of rock mass quality,14 indexes were selected and classified according to their hierarchy.Meanwhile,membership degree was expressed as normal function,and the weight of indexes were determined by two-stage evaluation methods to evaluate the deep rock mass quality.This method overcame the disadvantages of traditional methods to enable a more reliable evaluation result.Taking the-555 mlevel of Sanshandao Gold Mine for an example,the rock mass quality was concluded to class III,which was in accord with the actual investigation,therefore proved the correctness and rationality of this method.
