| 摘 要： | 针对露天边坡的稳定性问题,首先利用玫瑰花图和极点等密度图对结构面产状进行统计分析,然后结合边坡的地形地貌、地层岩性以及结构面发育程度等多方面因素得出对边坡稳定性起控制作用的优势结构面,并采用赤平极射投影对边坡的稳定性进行定性分析。结果表明,利用优势结构面判断矿山边坡是否稳定具有一定的可行性。

| Abstract: | Aimed at slope stability for open-pit mines,the orientations of structural plane were used for statistical analysis by rose diagram and pole and contour plots diagram.Then the preferred structural planes were obtained based on many factors,including the terrain and geomorphic characteristic of slope,the type and property of rock and the developing degree of structure plane etc.The stereographic projection method was applied to evaluate and analyze the stability of open-pit mines slope qualitative.Results showed that analysis of slope stability for open-pit mines based on preferred structural plane enjoyed a relative good feasibility. |
