Analysis of Surrounding Rock Stability tunnel factor Based on Rough Set Theory

摘要

We collected from the literature and analyzed 19 groups tunnel rock classification data, combined with data mining functions of rough set theory and attribute reduction capability, factor analysis model was established based on rough set theory. After 19 sets of data attribute reduction, extraction equivalence classes, calculated the attribute importance and weight, got the order of the stability factor of the tunnel, to provide data for the reference when the tunnel design and construction.
