摘　　要：为了揭示露井联采条件下边坡岩体变形破坏规律,结合平庄西露天矿工程实际,基于强度折减法,应用RFPA-SRM模拟岩体的变形破坏过程,分析了边坡的稳定性,表明受到双重采动的影响,边坡岩体的变形加剧,稳定性下降。该成果对露井联采矿山具有一定的参考价值和指导意义。To investigate the deformation and failure of slope under surface-underground combined mining conditions, a study was conducted at Pingzhuang＇s Western Open-pit. Based on strength reduction method, the processes of deformation and failure of slope under combined mining was simulated with RFPA-Slope and the slope stability is analysed. The study shows that the deformation aggravates and the slope stability declines with underground mining. The result is useful in surface-underground combined mining operations.
