Mixed Face Tunneling on Melbourne Underground
Adequate preliminary investigation, continued monitoring of ground conditions and construction procedure by the engineer, and a resourceful contractor combined to result in the economical design and construction of a four-track (double-under-double-over) rapid transit railway project in Melbourne, Australia. One tunnel contract required a variety of heading-and-benching-type operations to overcome mixed face conditions, with the soft ground being either on top, underneath, or in the middle of the face. Close monitoring of the tunnel construction by the engineer, skillful execution of the work by the contractor, and a good specification, permitted several variations of the original design resulting in economies.
