| Abstract: | 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.lt 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. |
