| Abstract: | Using Shiziyang Turmel in Guangshengang PDL as an example, this paper briefly introduces the initiation process under this project＇ s geographical conditions. The risk control techniques for slurry shield initiation are related in detail from the aspects of tunnel portal sealing and dismantling, installation of lead rail and negative tube piece, setting up of slurry pres- sure, cut water pressure control. The precontrol measures for the three big risks in initiation are pointed out as well. |
