引洮工程隧洞掘进机(TBM)施工质量控制重点分析及对策

Analysis on Key Points to Control Engineering Quality of Tunnel Constructed by TBM in Tao River Delivery Project and the Countermeasure

以引洮工程为例,分析了隧洞衬砌管片生产与安装、豆砾石回填灌浆、不良地质洞的TBM掘进与支护的重点和难点,提出了监理工作中应采取的措施。

Taking the Tao River Delivery Project as an example ,this paper analyzes the key points and diffculties including： manufacture and installation of tunnel lining segment,grouting in backfill gravel,excavation by TBM and support in bad geological condition of tunnel,at last,presents some countermeasure that must be adopted in supervision work.
