摘要
通过对某矿山总体边坡和局部台阶边坡分别进行稳定性极限平衡计算及数值分析,对设计边坡进行稳定性评价,调查边坡现状,重点查明滑坡的原因,针对潜在不稳定性提出了优化边坡角或边坡整治的建议,同时对边坡靠帮过程控制进行了分析研究,提出了采用小孔径预裂爆破的必要性,为改善边坡现状及保证边坡的稳定性奠定了基础。
The overall slope and local step slope are conducted by stability limit equilibrium calculation and numerical analysis respectively. Stability of the design slope is evaluated and the situation of the slope is investigated so as to understand the causes of landslide. According to the potential unstable of the slope,the suggestions of optimum slope angle and slope governance are proposed,besides that,the control technology of end-slope process is analyzed,the necessity of using small aperture pre-splitting blasting is discussed. The above research results lay the foundation of improving the state of slope and ensuring the stability of slope.
