Abstract Research purposes: With a total length of 13 256 m, Dabieshan tunnel on Hefei -Wuhan Passenger Dedicated Line isone of the controlling works of the railway. Safe and rapid construction of Dabieshan tunnel is essential to completion of Hefei-Wuhan Passenger Dedicated Line on time. Therefore, the effective construction technologies and construction methods must be adopted so as to realize rapid construction of the tunnel.
Research conclusions:The successful construction method adopted for Dabieshan tunnel is presented in the paper. It shows the rapid tunnel construction can be achieved if the construction organization is reasonable, the critical issues are focused on, the strict management is implemented, and the drill and blast technology is used along with ordinary machinery. The average daily drilling ratio of Dabieshan Tunnel is 7. 5 m, with the maximum monthly drilling ratio of 240 m.
