Abstract

Recently, the application of High-Power mechanized tunnelling technology has been expended around the world. Especially, High-power Modern TBM machines are used in a successful results. Essential for the great success of this modern TBM in difficult rock conditions are based on the development of machine power, suitable better cutter developments, and also developed assesment technology regards on the extensive site investigations. OPP (Owner Procurement Process) system is a proven alternative contract delivery method that is potentially applicable to many tunnel projects. Using the OPP, the owner specifies and procures the TBMs and tunnel lining in advance of the tunnel contract procurement and provides TBM to a tunnel contractor with a goals of reducing project risks and accelerating project schedule. Depending on the blasting vibrations and noises, mechanized tunnelling will be more important particularly in city areas.

세계적으로 Modern High-Power TBM을 이용한 터널공사가 점점 많아지고 있다. 특히 오늘날의 고성능 TBM의 개발로 많은 터널공사에서 성공적인 결과를 가져왔으며, TBM 동력의 향상과 커터 등 면판설계 기술의 발달, 및 TBM 굴진율 예측 소프트 웨어의 사용 등으로 터널공사의 자동화, 기계화가 이뤄 졌으며, TBM 장비조달은 OPP 방식을 이용한 발주자 직접 구매 방식이 TBM 선진국에서 효과적으로 사용되고 있다. 최근 많은 나라에서 환경 민원 등의 문제로 인해 도심지의 발파공법사용이 금지되어 TBM을 이용한 터널의 기계화 시공이 세계적인 추세이다.
