摘要
以某开采铁矿为研究对象,基于有限元分析法,进行了矿山边坡自动数值建模与分析研究,并对边坡的力学特性进行了分析,综合各单元的平衡方程得到了有限元模型的整体平衡方程。采用实例验证的方式,选取了模型参数敏感性和安全系数2个指标,分别验证了所研究方法的性能,结果表明,本方法具有一定可行性和实际应用价值,为岩土工程研究提供了参考依据。
With an iron mine taken as the research object,an automatic numerical modeling and analysis were performed for the mine slope by using the finite element analysis method,and the mechanical properties of the slope were also analyzed.An integrated equilibrium equation was obtained for the finite element model by the combination of the equilibrium equation of each unit.Sensitivity of model parameters and safety factor were selected to practically verify the performance of this research method.It is found that this method,being feasible and practical in the application,can provide a reference for geotechnical engineering research.
