摘要: 以新建南广铁路项目中的北岭山隧道为工程背景,选用大型有限元软件ANSYS建立软弱围岩段深埋宽长隧道施工模型,对该隧道D3K393+080段进行了数值模拟分析,得出隧道循环施工的应变规律,通过与现场监控量测数据对比,得出与工程实际数据接近的结果。分析表明,本次模拟选用的模型及参数基本合理,可为山岭隧道中类似软弱围岩段的设计和施工提拱一定的参考。

Abstract: The construction process of the Beilingshan Tunnel Section at Station D3K393+080 in the NanGuang Railway Project is numerically simulated by using the commercial finite element software ANASYS. The characteristics of this tunnel are the deep embedment, wide crosssection, and long alignment in the soft rock mass. The simulated deformation distributions are compared with the construction monitoring results. It is concluded that the simulated results are similar to the monitored values. Therefore, the design parameters selected for the analysis are reasonable and the analysis procedure can be used in the tunnel construction in the mountain areas.
