Abstract:The classification result of surrounding rock quality is important to select the road-header as the tunnel excavation method or not,so the classification method should be proposed. Firstly,a classification standard of surrounding rock quality was presented based on the instantaneous cutting rate(ICR),which can comprehensively reflect the influence of engineering geological condition and mechanical equipment factors on tunnel milling excavation. Secondly,the influence of the affecting factors and the evaluation indexes,their fuzzy and hierarchical characteristics on the classification result of surrounding rock quality was discussed. Then,a three-stage fuzzy synthetic judgment model of classify surrounding rock quality for tunnel excavation with road-header was suggested,and a method for determining the membership degrees and weight vectors of continuous and discrete evaluation indices was proposed. A corresponding strategy was also proposed to reduce the subjectivity of determining the membership degrees and weight vectors. Finally,the proposed method was applied to three different practical projects,and comparison between the calculation and measured results shows that the proposed method is feasible and reasonable.
