- 摘要:
- 为了探究控制性断层对露天边坡稳定性的影响，以我国某大型露天铁矿采场东北帮边坡为背景，通过工程勘察获取地质构造与岩性数据，采用赤平投影法分析边坡潜在破坏模式，开展边坡二维稳定性计算与三维数值模拟，系统探究控制性断层影响下边坡稳定性及危险区域。研究结果表明：边坡整体破坏模式以折线型破坏和圆弧型破坏为主；清除区域滑体后，1 404 m平台上部边坡处于稳定状态，但在F107、F17断层影响下Ⅱ区下部边坡处于欠稳定状态，存在大规模滑坡风险。研究结果可为后续边坡治理及安全高效开采提供参考。
- Abstract:
- In order to explore the influence of controlling faults on the stability of open-pit slopes,this paper takes the northeast slope of a large open-pit iron mine in China as the background.The geological structure and lithology data are obtained through engineering investigation,and the potential failure mode of the slope is analyzed by stereographic projection method.The two-dimensional stability calculation and three-dimensional numerical simulation of the slope are carried out,and the slope stability and dangerous area under the influence of controlling faults are systematically explored.The results show that the overall failure mode of the slope is mainly broken line failure and circular arc failure.After clearing the regional sliding body,the upper slope of the 1 404 m platform is in a stable state,but the lower slope of zone Ⅱ is in an unstable state under the influence of faults F107 and F17,and there is a risk of large-scale landslide.The research results can provide reference for subsequent slope treatment and safe and efficient mining.
