摘要
文章利用非线性有限元数值计算模型,对宝塔山隧道不良地质段开挖施工过程中的围岩应力及位移变化情况进行了模拟分析。结果表明,隧道围岩应力及变形均满足规范要求,处于稳定状态。
Using non-linear finite element numerical computation model,the article made an analysis of the stress and displacement of surrounding rock in excavation and construction of the bad geological section of Baotashan Tunnel.It is proved that both the stress and the transformation of the surrounding rock of the tunnel satisfy the requirements of the specification,with normal stability.
