| Abstract: | A method based on rough set theory and fuzzy assessment is proposed to classify the stability of rock-mass slopes, the evaluated indexes are selected by using knowledge reduction method of rough set theory. The problem of weighting coefficient is converted into that of significance estimating on the attributes in rough set. And a classification model of the stability of rock-mass slopes is established. The classification model, reflecting the complexity situation of the stability of rock-mass slopes objectively, is effective, reliable and available to the classification of the grade of the stability of rock-mass slopes, and easy to operate. |
