Abstract

This paper presents the shield TBM technology in soft ground tunnelling. In order to perform this study, a scale model test was carried out using the developed small scaled shield TBM machine. The various instrumentations were conducted during the simulation of tunnelling. In addition, the ground behavior due to the shield TBM operation parameters was measured during the simulation. Based on the simulation results, the stability of the ground was evaluated and the fundamental shield TBM tunnelling technique in the soft ground was suggested. In conclusion, design’s reliability through laboratory small scale model test about Shield-TBM section was obtained, and both the improvement plan for safety during construction and the construction plan for securing airport runway’s safety during tunnel passing by Shield-TBM propulsion were suggested.

본 논문에서는 연약지반에 건설되는 Shield TBM 터널의 시공기술을 제시하였다. 이 연구를 수행하기 위하여 Shield TBM 장비를 축소･제작하여 축소모형 시험을 수행하였으며, 쉴드터널 굴착을 모사하기 위하여 다양한 장비들이 적용되었다. 또한 축소모형 시험 중 Shield TBM 장비로 인해 발생되는 지반의 거동을 계측하였으며, 지반의 안정성은 시뮬레이션 결과를 토대로 평가하였다. 이를 바탕으로 쉴드터널의 안전한 시공을 위한 기초자료로 활용하고자 한다. 결론적으로 Shield-TBM 구간에 대한 실내축소모형시험을 통하여 설계의 신뢰성을 확보하고, 시공 시 안전을 위한 개선사항 등과 특히, Shield TBM 추진시 쉴드터널이 통과하는 공항 활주로의 안정성을 확보하기 위한 시공방안을 제시하고자 한다.
