摘要
分析了国春铁矿地下开采对大秦铁路路基稳定性的影响因素,建立了适于采矿工程模拟的FLAC数值模拟模型。通过数值模拟分析,计算出铁路附近的应力变化数值,其结果对矿山建设和安全生产具有重要的参考价值。
This paper pays attention to the factors resulted from the iron underground digging, which may have bad influence on the base stability of Daqin Railway. Meanwhile, the FLAC numerical simulation model is established to adapt the simulation of the mineral industry. The calculation of changers of stress near the railway can be traced to the analysis of the numerical simulation. The result of simulation is going to he a good reference to the mine construction and safety production.
