A STUDY ON RAPID NATM TUNNEL DRIVING BY EARLY-HIGH-STRENGTH SHOTCRETE SUPPORT SYSTEM

Rapid tunnel driving largely contributes to reduction of construction cost and period. Therefore, the authors study rapid NATM tunnel driving for mechanical excavation applied to soft rock and inspected it in the tunnel site. The characteristic of this method is to adopt ‘early-high-strength shotcre...
