Abstract

This paper is a study on the development of equipment system to obtain data on stability in excavation of sharp curve section of Shield TBM. Shield TBM equipment is being used a lot recently for tunnel excavation. Excavation may result in inevitable detours by buildings above the ground or existing underground structures. Pre- construction simulation is required to verify the stability of the construction in case of this. Therefore, it is necessary to establish an automated control system through the development of this equipment system and conduct simulation through simulation of excavation model in the sharp curve section. A system shall be developed to control the left and right angles and thrust of the equipment, and to view data on the earth pressure and propulsion pressure of the equipment in real time during excavation. With this system, the necessary data can be collected for field testing through excavation method and excavation simulation by angle. It is expected that it will be very useful in assessing the actual Shield TBM by conducting a scale-down model experiment.

본 논문은 쉴드 TBM의 급곡구간 굴착 시 안정성에 대한 데이터를 얻기 위한 장비 시스템 개발 연구이다. 최근 터널 굴착에 쉴드 TBM 장비가 많이 활용되고 있다. 굴착 시 지반 상부의 건물이나 기존 지하 구조물에 의해 불가피 하게 우회해야 할 경우가 발생할 수 있다. 이러한 경우에 대비하여 시공의 안정성을 확인하기 위해 시공 전 사전 시뮬레이션이 필요로 한다. 그러므로 본 장비 시스템 개발로 자동화 제어시스템을 구축하여 급곡구간 굴착 모형 시뮬레이션을 통해 모의실험을 진행한다면 안정성을 높일 수 있을 것이다. 장비의 좌 ‧ 우 각도 및 추력 등을 제어하며 굴착 시 장비에 받는 토압, 추진압에 대한 데이터를 실시간으로 볼 수 있도록 시스템을 개발하여야 한다. 이 시스템으로 굴착 방법과 각도 별 굴착 시뮬레이션을 통한 현장실험에 필요데이터를 수집할 수 있다. 실제 쉴드 TBM 공사 전 축소모형 실험을 통한 평가 시 매우 유용하게 활용될 수 있을 것으로 기대된다.
