摘　　要：以高岭煤矿复杂高边坡为研究对象，针对多种加固组合模式，运用 MIDAS 软件进行数值模拟对比试验研究，分析边坡内的应力分布及变形特征，结合综合监测验证了加固效果。研究结果表明：填土高边坡的稳定性较差；针对破坏机理，采取的相应加固措施效果良好，防止了边坡后缘出现的拉裂现象；在潜在的边坡滑动带创造的中部锁固体，加强了下部潜在隆起带土体强度，同时限制了临空面的位移滑动。这些措施调整了边坡整体应力分布状态，边坡的稳定性得到显著加强。With the Gaoling coal mine complex high-slope as the research object, aiming at various reinforcement combined models, make numerical simulation comparison test using the MIDAS software, analysis stress distribution and deformation characteristics of the slope, combined with the comprehensive monitoring to verify thereinforcement effect.The results show that： poor stability of high slope filling; according to the failure mechanism, adopt corresponding reinforcement measures so as to has good effect, prevent the cracking phenomenon at the posterior edge of slope, in the potential slope slide belt create the central lock solid. strengthen the soil strength of the lower potential uplift belt. At the same time limit the free surface displacement slip, these measures adjust the overall slope stress distribution, stability of the slope has been significantly strengthened.
