摘要 针对传统评价方法所存在的缺陷,运用可拓工程方法,在物元理论和可拓数学理论的基础上建立了岩体质量评价的物元模型,并采用引入了距离函数的组合赋权法计算物元模型中各评价指标的权重。研究结果表明:组合赋权法将层次分析法计算的主观权重和熵权法计算的客观权重结合起来所确定的组合权重科学合理;另一方面,岩体质量的可拓评价不仅能较好地反映岩体的质量等级,还能反映岩体质量等级的程度以及与其他质量等级的"距离",具有较好地适用性。通过实际矿山岩体质量等级的关联度计算,对新田岭钨矿小板垅矿段和金猫矿段矿岩及围岩岩体质量进行了可拓学评价,评价结果与现场实际相符。 In view of the shortcomings in the traditional evaluation methods, a matter-element model was established for rock mass quality evaluation. Meanwhile, a combination weighting method with a distance function was used to calculate weight of evaluation indicators of matter element model. The result shows that a more scientific and rational weight can be obtained by the combination weighting method, which combines the subjective weight from analytic hierarchy process and the objective weight from entropy-weight method. Then based on the calculation of correlation degree for rock mass rating, the quality of rock mass and surrounding rock in some sections of Xintianling Tungsten Mine were all evaluated by using extenics, with evaluation results in conformance with practical situation.
