| 岩体是由结构面和岩石组成的复合地质体，结构面的存在会在一定程度上降低岩体质量和露天矿山边坡稳定性。本文总结了常见的边坡破坏模式，以某露天高陡边坡为研究对象，开展基于Sirovision系统的岩体结构面调查与统计分析工作，获取了研究区域内48条结构面。采用K-means聚类算法得到3组优势结构面产状，发现区域边坡有发生楔形体破坏的可能，经计算楔形体在3种不同工况下的安全系数满足规范要求，表明区域边坡处于较为稳定状态。 |
| 英文摘要: |
| Rock mass is a composite geological body composed of discontinuities and rock， the existence of discontinuities will reduce the quality of rock mass and the stability of open-pit mine slope to a certain extent. This paper summarizes the common failure modes of slope， takes an high and steep slope in an open-pit mine as the research object， carries out the investigation and statistical analysis of rock mass discontinuities based on the Sirovision system， and obtains 48 discontinuities in the study area. The K-means clustering algorithm was used to obtain the occurrence of three groups of dominant discontinuities， and it was found that wedge failure was possible in the studied area. The calculated safety factor under three different conditions met the standard requirements， indicating that the slope was in a relatively stable state. |
