| 摘 要： | 为经济有效地控制高地应力软岩隧道施工大变形,以木寨岭铁路隧道施工为例,通过建立数值分析模型,对不同初期支护厚度、锚杆长度及钢架间距的变形控制效果进行对比分析,得出了木寨岭隧道开挖变形规律,并对初期支护参数进行了优化,可为类似地质及施工环境下的隧道施工提供技术参考。

| Abstract: | The deformation control effect of different primary support thicknesses,different anchor bolt lengths and different steel arch intervals are compared and analyzed by means of numerical simulation analysis,with the construction of Muzhailing tunnel as an example.In the end,the regularity of deformation of Muzhailing tunnel induced by excavation is obtained and the primary support parameters are optimized.The paper can provide reference for similar projects in similar geology conditions and similar construction environment. |

| Keywords: | Muzhailing tunnel numerical simulation deformation primary support parameter optimization |
