基于粗糙集的隧道围岩质量可拓学评价
|
摘要
将粗糙集理论与隧道岩体质量评价相结合,把权系数问题转化为粗糙集中属性重要性评价问题,建立了关于隧道岩体质量评价的关系数据模型。通过实际隧道岩体质量等级的权系数计算,对隧道岩体质量进行了基于粗糙集的隧道围岩质量可拓学评价,并将评价结果与实际的评价结果对比分析,认为基于粗糙集的隧道围岩质量可拓学评价能反映隧道岩体的工程特性。
The rough set theory is combined with the tunnel surrounding rock evaluation,the problem of weighting coefficient is converted into that of significance estimating on the attributes in rough set,and a relation data model about tunnel surrounding rock evaluation is established. By calculating the weighting coefficient of every grade of the practical tunnel,the tunnel surrounding rock is evaluated by the extenics theory based on rough set. And compared with the practical evaluation results,the results obtained by the extenics theory based on rough set can reflect well the engineering characteristics of the tunnel rock mass.
