摘要
利用dips软件,结合对某露天煤矿运煤大道的节理控制性黄土边坡野外实测数据进行赤平投影分析,得出该区域黄土边坡破坏模式主要为倾倒破坏和楔形体破坏,平面滑坡较少。根据dips软件分析成果,运用swedge软件进行优势节理面楔形体破坏分析,提出对于该区域黄土边坡应加强对倾倒破坏控制节理和可以组成楔形体破坏黄土节理的调查与监测,并在节理扩展前加以采取防治措施。
Using dips software,combined with the analysis of field measuring data in an open-pit mine＇s jointed controlled loess slope of coal transportation,the paper obtained that the main loess slope failure modes is toppling failure,wedge failure in this region though analysis of stereographic projection,the planar landslide is less.According to the dips software analysis results,investigation and monitoring should be strengthened for the dumping of damage control joint and formed wedge failure＇s loess joint by using swedge software.prevention and control measures should be taken before the joint expanded.
