Study of Tunnel Surrounding Rock Classification Based on Drifting Degree and Uncertainty Measurement
Based on contrast analysis of tunnel surrounding rock classification method, five basic indicators were selected as evaluation factors. Evaluation matrix was constructed by uncertainty measurement theory. Weight was established by introducing drifting degree concept. The principle of maximum membership degree was choosed as evaluation criterion.Then a tunnel surrounding rock classification model was built.This comprehensive evaluation method made full use of its own parameters and evaluation standard to completely avoid the subjective influence of traditional weights determination and the sample set, making itself more objectivity and accuracy, having a strong operability. The practical engineering showed that this model applied to tunnel surrounding rock classification was feasible and had certain superiority, providing a new way for tunnel surrounding rock classification.
