摘要
介绍了国内首台单护盾隧洞掘进机(TBM)在甘肃省引洮供水一期工程总干渠7号隧洞的应用,针对单护盾TBM在软岩洞段掘进施工时碰到的一些主要问题提出了解决对策,为今后TBM遇到类似围岩地质条件下掘进施工提供一些借鉴和帮助。
The paper introduces the application of single shield TBM to excavate tunnel in main general canal of Tao River Diversion Project（first stage）in Gansu Province.It is the first time to use this machine in our country.Aiming at the main problems that are encountered during using this machine to excavate weak rock stratum,the paper presents some countermeasures.It can provide reference and help for similar construction conditions.
