| Abstract: | Options for the casting of the arc-shaped cradles for TBM stepping of West Qinling Tunnel are analyzed on basis of casting speed,arc surface quality and economical benefit,so as to shorten the construction period.In the end,the option of casting the arc-shaped cradles by means of sliding formwork is selected.The maximum daily casting rate has reached 160m and the assembly and stepping of TBM are guaranteed,which demonstrates that the casting method adopted is feasible. |
