摘要
文中分析了复合采动影响下边坡岩体的移动特点 ,研究两种开挖效应的相互作用机理和边坡岩体破坏机制。在此基础上 ,应用随机介质理论 ,推导出地下开挖在边坡岩体内所产生的形变力 ,并依据边坡岩体稳定性计算理论 ,最终推导复合叠加采动影响下边坡稳定性计算方法。同时应用随机介质理论 ,推导出复合采动影响下地面变形的预测模型和特殊地质条件下变形的预测方法。结合实例对变形参数的计算方法等内容进行了分析和研究 ,并对后续开采将产生的变形值进行预测。
Moving behavior is analyzed under combined underground and open pit mining. Interaction and failure mechanism of slope rock mass is studied due to two types of mining effect. Deformed force for slope rock mass is derived from random medium theory on the basis of analysis for these mechanism. Calculating method of slope stability is applied under combined mining according to calculating theory of slope rock mass stability. Meanwhile, prediction model of underground deformation and predicting method of deformation for special geological factor is deduced under combined mining with random medium theory. Finely, the deformation value is predicted combined case-history with study of calculating method for deformed parameter due to continuing mining.
