초록
일반적으로 리스크 관리는 리스크 확인, 리스크 분석, 리스크 평가, 리스크 대책, 리스크 재평가를 포함하는 일련의 과정으로 구성된다. 본 논문에서는 쉴드 TBM 터널에서 발생 가능한 리스크 요인들을 여러 문헌 자료와 워크샵을 바탕으로 조사하였다. 리스크 요인들은 지질 요인, 설계 요인, 시공 관리 요인으로 구분되었다. Fault Tree도는 리스크들을 커터, 기계 구속, 배토(굴진), 세그먼트과 관련된 4그룹으로 분류하여 작성되었다. FT도로부터 12가지 리스크 아이템을 확인하고 각각의 발생확률을 구하였다.

Abstract
In general, risk management consists of a series of processes or steps including risk identification, risk analysis, risk evaluation, risk mitigation measures, and risk re-evaluation. In this paper, potential risk factors that occur in shield TBM tunnels were investigated based on many previous case studies and questionaries to tunnel experts. The risk factors were classified as geological, design or construction management features. Fault Tree was set up by dividing all feasible risks into four groups that associated with: cutter; machine confinement; mucking (driving) and segments. From the Fault Tree Analysis (FTA), 12 risk items were identified and the probability of failure of each chosen risk item was obtained.
