摘　　要：本文提出一种基于有限元法的露天采场边坡稳定性综合评价方法。以某露天采场为研究对象,构建了边坡的几何模型,选取了合理的岩土体力学参数,并通过有限元法对边坡的应力、位移及安全系数进行了数值模拟与分析。在多种荷载组合工况下,计算了边坡的安全系数,并识别出不同剖面的失稳模式。研究结果表明,该方法能够准确反映边坡在自重、爆破振动及地震荷载下的力学行为,有助于提高采场的安全性和运营效率。This article proposes a comprehensive evaluation method for the stability of open-pit mining slope based on finite element method.Taking a certain open-pit mining site as the research object,a geometric model of the slope was constructed,reasonable rock and soil mechanics parameters were selected,and the stress,displacement,and safety factor of the slope were numerically simulated and analyzed using finite element method.Under various load combinations,the safety factor of the slope was calculated and the instability modes of different profiles were identified.The research results indicate that this method can accurately reflect the mechanical behavior of slopes under self weight,blasting vibration,and seismic loads,which helps to improve the safety and operational efficiency of mining sites.
