摘要
采用有限元数值模拟软件ADINA对隧道开挖和支护变形进行分析,根据隧道围岩变形特点,提出采用锚喷支护的形式对隧道进行二次支护。数值模拟结果表明:采用锚喷支护可以改变围岩受力状态,显著的减小隧道拱顶变形和两帮侧移。
This paper analyzed the tunnel excavation and shoring deformation using the finite element numerical simulation software ADINA,according to the deformation characteristics of tunnel surrounding rock,put forward using the anchor-plate retaining to make two supporting to tunnel.The numerical simulation results showed that using anchor-plate retaining could change surrounding rock stress state,significantly reduce tunnel vault deformation and two lateral.
