摘要
针对南芬铁矿地下硐室开挖与支护设计,采用有限元分析研究大跨度地下硐室施工的动态力学效应。结果表明,不同的开挖顺序,对围岩的稳定性具有显著的影响。
This paper approaches the excavating dynamic behavlour and support design for a large cavern in Nanfen Iron Mine using finite element method. The results show that the differences of stability of surrounding rock mass are markable for dlfferent excavating sequences.
