| Abstract: | The poor wall rock stability and steep grade of the exit section of Zhujiayan tunnel make tunneling hard, thus the supporting technology is applied to pre-reinforced measure. The long pipe ＆ shed designing parameters, casting param- eters and construction technic are introduced. It is proved to be successful to apply long pipe ＆ shed pre-reinforced sup- porting technology to treat Zhujiayan tunnel exit section, making the tunnel secure, reducing the construction time and ensuring its quality. |
