摘　　要：为研究反倾岩质边坡对露天矿边坡变形的影响,本文基于刚体极限平衡法,利用GeoStudio软件进行不同工况条件下的稳定性计算,结合合成孔径边坡雷达监测数据,对反倾岩质边坡的稳定性进行分析。结果表明:反倾岩质层状边坡对露天采场边坡的稳定性影响较小,采场边坡在自然、地震及爆破3种工况下,采区现状及年度计划均满足安全系数要求;采用合成孔径边坡雷达监测,结合现场监测数据情况,受冻土融化影响,区域受到自然沉降的影响而产生变形,刚体极限平衡法和合成孔径边坡雷达监测技术相互验证采场区域稳定性较好。研究成果可为该类边坡的灾害防控提供理论支撑。To study the influence of anti inclined rock slopes on the deformation of open-pit mine slopes,based on the rigid limit equilibrium method,stability analysis was conducted under different working conditions using GeoStudio software.Combined with synthetic aperture slope radar monitoring technology,the stability of anti inclined rock slopes was analyzed.The results show that the stability of the open-pit mining slope is less affected by the anti inclined layered rock slope,and the current situation and annual plan of the mining area meet the safety factor requirements under natural,seismic,and blasting conditions;Using synthetic aperture slope radar monitor-ing,combined with on-site monitoring data,the area is affected by frozen soil melting and natural settlement,resulting in deformation.The rigid body limit equilibrium method and synthetic aperture slope radar monitoring technology mutually verify that the stability of the mining area is good.The research results can provide theoretical support for disaster prevention and control of such slopes.
