Construction Technology for Shallow- buried Eccentrically Compressed Tunnel Entrances |
| |
| Abstract: | A shallow-buried eccentrically compressed section of tunnel entrances adopts surfacing grouting,surface anchor bolt and anchor bolt spray to strengthen stratums as well as technical measures of eccentrically compressed lining for the tunnel structure.The result shows that to adopt construction technology can effectively hinder the deformation and cracking of tunnel and surface settlement to ensure the tunnel safety. |
