摘要

节理岩体结构面的优势产状是进行Mnote-carlo模拟和岩体稳定性分析的基础。玫瑰花图、等密度图等传统的图形分析方法比较粗糙，其结果只是相对的优势组数划分，无法准确地给出结构面的优势产状，使得分组结果在实际中应用不便。为弥补上述不足，采用改进的动态聚类分析方法，构造空间直角坐标系，以结构面的单位法向量表示其产状，并根据球面上两点之间的球面距离对结构面产状进行分类判定。将该方法应用于三峡库区巴东新县城铜盆溪桥东头高切坡结构面优势产状分析中。结果表明，采用改进动态聚类分析方法结果可靠，分类合理，可以较准确地确定结构面的优势产状。

Abstract

The analysis of dominant orientations of discontinuities is a basic work for a further study on simulating with Monte-Carlo method and conforming the stability of rock mass. Traditional analysis of plots method is insufficient and inadequate. The result is only a simply classification of the orientations

and is inconvenient to be applied in practice. Because of the deficiency of traditional analysis method

a dynamic clustering algorithm is developed. According to the rule of right hand

a three-dimensional field coordinate system is constructed. A unit normal can be used to represent the orientation of discontinuity. Then the orientations are classified by the dots' spherical distance. A data investigated from a slope in the new town of Badong County in the Three Gorges Reservoir is used to be a case study. The study shows that the results of dynamic cluster algorithm are reliable and reasonable. And the dominant orientations and classification are more precision.
