基于粗糙集理论的隧道围岩模糊综合评判

摘要

Aimed at the problem of tunnel surrounding rock classification, rough set theory is introduce to fuzzy comprehensive assessment. Determining weighting coefficient was translated into estimating significance of attributes among rough set and it is established of tunnel surrounding rock classification model with fuzzy comprehensive assessment based on rough set. Finally, improved fuzzy comprehensive assessment is applied to the practical engineering and the evaluation results shows that the method can more reflect the engineering characteristics of tunnel rock.%针对隧道围岩分类问题,将粗糙集理论引入到模糊综合评判中,将各指标的权重转化为粗糙集理论中各属性的重要性,建立了基于粗糙集理论的隧道围岩模糊综合评判模型.最后,将改进后的模糊综合评判应用于实际工程中的围岩分类问题中,结果表明,该方法可较为真实地反映隧道岩体的工程特性.
