A Study on Design Program of East Qinling Super-long Tunnel of Xi'an-Nanjing Railway |
| |
| Abstract: | East Qinling Super-long Tunnel has a total length of 12,268m. According to design, the twin-track tunnel with parallel heading shall be excavated using drill and blast method. Form concrete lining shall be applied to the sections 35m to entrance and exit, and composite lining shall be applied to the remaining part. Shotcreting, anchor bolts and wire mesh are principal supporting means assisted with steel frame. The tunnel is the control project of Xi'an-Nanjing Railway, and is scheduled to be completed in 58.32 months. Design program of the tunnel is illustrated from geological characteristics, selection of program, and structural design, etc. |
