摘要
本文利用大型有限元软件ANSYS对隧道合理的开挖进尺进行三维数值模拟,得出不同开挖进尺对有衬砌和无衬砌情况下隧道围岩与支护结构的位移、应力的变化规律,据此合理确定隧道的开挖进尺,充分发挥围岩的自承能力,优化隧道的施工设计,降低建设成本。
In this paper reasonable tunnel excavation footage for 3D simulation has done using large-scale finite element analysis software ANSYS. We come to the change regularity, the lining and unlined cases, that different excavation footage on stress and displacement of surrounding rock and supporting structure of tunnel. Accordingly to determine reasonable tunnel excavation, give full play to the bearing capacity of surrounding rock, optimizing the construction design of the tunnel and reduce construction cost.
