| 摘 要： | 在对比分析各类岩体质量评判方法的基础上,针对影响地下工程岩体质量的关键因素,选取其中的6项基本指标作为地下工程岩体质量评判的基础.然后采用距离判别分析的思想确定岩体评价指标的隶属度,并引进变异系数法与专家评分相组合来确定各指标权重,建立了相应的模糊综合评价模型.该方法使得距离判别关系定量化,避免单纯距离判别分析方法中的模糊不确定性带来的误差.通过对三山岛金矿深部岩体进行的工程应用表明,该方法对于地下工程岩体分级具有很好的适用性与合理性.

| Abstract: | Based on a comparative analysis of different rock mass quality evaluation methods,six basic indicators of the key influencing factors are selected as the basis for rock quality evaluation in underground engineering.The membership function of each indicator is determined by distance discriminant analysis,while the corresponding weights are then determined by the combination of variation coefficient and expert grading methods.Thus,a fuzzy comprehensive evaluation model is established.This method makes the dis... |
