以白云鄂博铁矿东矿C区岩体节理产状为研究对象，通过构造空间直角坐标系，采用基于Euclidean距离度量标准的系统聚类法对反映节理产状的单位法向量进行分类，选用合适的分布函数描述各组节理，并对各组节理的概率分布模型进行卡方检验。结果表明，采用系统聚类法能较好反映现场节理产状，准确给出岩体节理分类方案，消除人为判别模糊性。基于聚类分析结果，结合边坡参数，采用赤平极射投影法进一步确定边坡最可能失稳模式，为调整边坡设计参数，控制边坡灾害提供依据。

Based on Euclidean distance, the hierarchical cluster method was adopted to analyze the unit normal vectors converted from the dip angle and dip direction of Bayan Obo East Iron Mine on the premise that the rectangular coordinates system was construc-ted. A proper distribution model was chosen to describe each joint group, and its validity was verified by chi-square test. It is found that the hierarchical cluster method can analyze the joint attitude accurately and provide reasonable classification of joint attitude without any uncertainty caused by human judgment. Based on the hierarchical cluster result of rock mass joints and slope design parameters, the most probable slope instability mode is determined by the stereographic horizon projection technique, which provides a basis for ad-justing slope design parameters and controlling slope disaster.
