ISODATA Fuzzy Clustering Analysis of Slope Stability Xu Chuanhua Zhu Shengwu Fang Dingwang ( Maanshan Institute of Mining Research) Abstract   The factors that influence the slope stability are characterized by complexity ,randomness and fuzziness. The conventionally used fixed - value analysis method doesn’t consider the uncertainty that practically exists ,while the fuzzy clustering model that is established by using the instability and stability cases of slope engineering considers the influ2 ence of various factors. The calculation analysis shows that the application of this model in evaluating slope stability can achieve good effect.
