| The use of TBM has been rapidly increased in recent years since TBM has been introduced to Korea in 1985 and Korea came to occupy 27% of TBM holding ratio in the world. Despite a lot of experience, study on promoting the efficiency of TBM excavation is insufficient. The factors that influence the efficiency of excavation are the mechanical farttor geotechnical factor and management factor. The study on the efficiency of excavation has focused on the improvement of mechanical factor. But geotechnical factor is also very important and by this factor engineer can estimate the applicability of TBM. The purpose of this paper is to understand the effectiveness of TBM excavation for vari orts rock quality by analysing relations between rock quality and TBM excavation. |
