摘要: 针对西藏邦铺露天矿基建边坡的稳定性问题,首先在矿区平峒中进行结构面现场测量,对结构面产状进行统计分析得到玫瑰花图、等密度图和透视投影图,再结合露天矿基建开挖初设边坡的地形地貌、地质构造以及结构面特征因素得出对基建开挖初设边坡稳定性起控制作用的优势结构面,进而采用赤平极射投影对基建开挖边坡的稳定性进行了定性分析。

关键词: 结构面统计, 优势结构面, 赤平投影图, 边坡稳定性

Abstract: In view of the stability problem of side slope in construction of Tibet Bangpu Open-pit Mine, the field measurement on the structure plane in tunnel of mining area was firstly made. And the roses diagram, the isodensity map and the perspective projection drawings were got through the statistical analysis of the occurrence of structure plane; Then, combing with the characteristics of landforms, geological structure and the structure plane of side slope in openpit mine, the preferred structure plane which control the stability of side slope was attained-Lastly, the qualitative analysis on the stability of side slope was made by the stereographic projection.

Key words: Structure plane statistics, Preferred structure plane, Stereographic projection, Slope stability
