露天煤矿滑坡灾变机理及控制对策研究

Study on landslide catastrophe mechanism and control strategy for open-pit coal mine

本文在边坡工程地质条件分析的基础上,确定了滑坡的主要类型及影响因素,并进一步分析了边坡滑坡灾变机理。采用非线性大变形有限差分软件FLAC对滑坡灾变演化进行了数值模拟研究,在研究的基础上提出了"预应力锚索框架梁+高压劈裂注浆加固边坡"的新技术,并通过数值方法和现场试验验证了方案的可靠性。

This paper defined the main types and key influencing factors of landslide,and analyzed landslide catastrophe mechanism on the basis of analysis on engineering geological condition of slope.The course of landslide catastrophe was numerical simulated by adopting the nonlinear,large deformation finite element software of FLAC.Based on the previous study,the new technology of ＂the pre-stress anchor frame beam and high press splitting and grouting to reinforce slope＂ was proposed,furthermore it＇s reliability was verified to be rational and effective through numerical simulation and field test.
