摘要
文章依托一单洞四车道公路隧道工程,采用有限元软件ANSYS,对特大跨度公路隧道施工中各个施工步骤的力学行为进行了数值模拟分析,评判围岩与支护结构在各个阶段的安全性与稳定性,并提出了设计与施工过程中应注意的问题。
Relying on a single-hole four-lane highway tunnel project, by using the finite element software ANSYS,this article conducted the numerical simulation analysis on the mechanical behavior of various construction steps in large-span highway tunnel construction, evaluated and determined the safety and stability of surrounding rock and supporting structural in various stages,and proposed the problems to be noted during the design and construction process.
