摘 要:采用模糊测度方法对大型露天矿节理化岩石边坡的稳定性进行了分析,利用BP神经网络确定模糊测度数学模型中的参数,进而分析在爆破振动影响下边坡的失稳程度。采用有限元(Ansys软件)模拟演算出边坡的潜在滑动面,同时利用Bishop法对有限元所演算出的潜在滑动面进行了计算,以此来综合预测分析边坡的稳定性。理论预测结果与矿山工程实际情况一致,表明本文方法适用于预测分析节理化露天矿边坡的稳定性。The fuzzy measure method is adopted to analyze the stability of jointed rock slope in large opencast mines and the pa rametersin the model are determined using the BP neural net work to analyze the instability of mine slope under the influence of the blasting vibration. The potential sliding surface of the slope is simulated and calculated by the finite element software (Ansys)and the Bishop method. Consistency of the actual situations of the mining project with the predicted results indicates that the proposed method has good practicability to forecast and analyze the stability of jointed rock slope in open pit mines.
