摘要
以山西某露天矿下盘岩质高边坡为研究对象,基于对该露天煤矿边坡工程地质的认识,结合实时监测记录和现场调查,采用杂交有限元-离散元法(FDEM)对该露天矿"2011-1005滑坡"进行数值模拟计算。通过数值计算模型,从连续到不连续的变形特征来描述岩石微裂纹聚合、裂纹发展和破碎岩石相互作用(接触、碰撞和反弹)的变形破坏过程,并将计算结果和实际边坡破坏物理特征进行对比研究,验证利用FDEM法对露天煤矿采场下盘边坡稳定性评价和数值模拟计算的可行性。
rock slope of some mine in Shanxi was taken as study object, based on the geological data, monitoring record and field investigation, FDEM was taken to conduct numerical simulation in 2011-1005 slope, the deformation damage process of Rock microcrack polymerization, crack development and rock interaction was described From continuous to discontinuous deformation characteristics, the calculation results and actual slope damage physical characteristics were compared and studied, proving the feasibility of numerical simulation of FDEM in measuring mine landslide outdoors.
