摘　　要：结合粗糙集理论与模糊C-均值(FCM)算法,提出一种边坡稳定性影响因素敏感性分析新方法。将边坡稳定性影响因素敏感性分析问题转化为粗糙集理论中的属性重要性评价问题,采用FCM算法离散连续属性数据,给出敏感性分析的具体算法。以圆弧型破坏边坡为例,对影响边坡稳定性的单因素与多因素敏感性进行分析,证明了该方法的可行性和有效性。A new method based on the rough set theory and the fuzzy C-means algorithm is proposed to analyze the sensitivity of the influencing factors for slope stability. According to this method, the problem of the sensitivity analysis of the influencing factors for slope stability is translated into the problem of evaluating significance of attributes among the rough set theory. The fuzzy algorithm is then introduced to discretize continuous attributes; and the assessment model is set up to achieve the sensitivity analysis. Taking the circular slip slope for example, the sensitivity analysis of the influencing single factor and multiple factors for slope stability is performed; and it is shown that the proposed method is feasible and effective.
