Abstract

The disc cutter mounted on the Tunnel Boring Machine (TBM) is subjected to cutting forces in three dimensions during rock excavation process. It is widely known that the cutting forces increased with the strength of the rock mass, while the rolling force can be significantly increased when the disc cutter encounters abnormal rotation. Therefore, the cutting force acts on the disc cutter provides important information because it represents the conditions of the rock mass and the disc cutter. For these reasons, several studies have been conducted to measure the cutter forces in real-time. This paper introduces the current status of research on the cutter force measurement of TBM disc cutters, which has been reported in the literature. It is judged that this paper can be a useful reference material when similar technologies are developed in Korea in the future.

TBM에 장착되어 암석을 절삭하는 디스크커터에는 암반을 굴착하는 과정에서 세 방향의 절삭력이 작용한다. 일반적으로 디스크커터의 절삭력은 굴착대상암반의 강도에 따라 증가하는 것으로 알려져 있고, 디스크커터가 여러 원인에 의해 정상적으로 회전이 이루어지지 않는 경우에는 회전력이 급격하게 증가할 수 있다. 따라서 굴착 도중 디스크커터에 작용하는 절삭력은 굴착의 대상이 되는 암반의 상태나 디스크커터의 절삭상태를 나타내는 중요한 정보가 될 수 있다. 이러한 이유로 해외를 중심으로 디스크커터의 작용력을 실시간으로 측정하기 위한 기술의 개발이 이루어지고 있으며, 본 연구에서는 현재까지 해외의 문헌을 통해 보고되고 있는 TBM 디스크커터의 하중계측에 관한 연구현황에 대하여 소개하고자 하였다. 향후 국내에서도 유사한 기술의 개발이 이루어지는 경우에 유용한 참고자료가 될 수 있을 것으로 판단된다.
