中文摘要: 将粗糙集理论与模糊集理论相结合,应用于边坡稳定性问题中，利用粗糙集理论中的知识约简方法挖掘评价指标。把权重问题转成粗糙集理论中的属性重要性问题，建立了关于边坡稳定性分级评价的关系数据模型。评价结果表明：预测等级比较客观地反映了边坡稳定性的复杂状况，且该方法操作简单，结果可信。

中文关键词: 粗糙集岩体边坡稳定性分级知识约简

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.

keywords: rough sets stability of rock-mass slopes classification knowledge reduction
