| Abstract: | Roof ripping is a key technology for tunnel construction in soft rock stratum. As shaft roof ripping construction for twin-track tunnel in coal shale stratum of Gui-Guang project＇ Tianpingshan tunnel, the authors introduce the construction technology, technical mote, construction organization and construction attention in detail. Due to deform- ation of soft rock and complex structure of trumpet section, the actions for assuring project quality and construction safety are put forward. |
