车站进入区间暗挖隧道开洞施工技术

Tunnel subsurface excavation techniques from the station to the interval

以奥体中心站向奥体中心站—奥林匹克森林公园站暗挖隧道进洞技术为例,介绍了在车站仅底板施作完二衬的情况下通过注浆对奥体中心站端墙洞顶周围土层进行改良加固技术,并运用监控量测手段,完成了由车站向区间的进洞任务。

Taking the tunnel subsurface excavation techniques from Olympic Sports Center Station to Olympic Sports Center Station--Olympic Forest Park Station as an example, the author introduces the improvement and the reinforcement technology of the soil layer around the end wall and the roof in Olympic Sports Center Station by grouting under the situation that the construction of secondary lining of the floor is completed, and finish the entrance tasks from the station to the interval by using the monitoring measurement.
