Zhong Xiaojie · Sichuan Building Science · 2011
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.
