Abstract

The construction method for Young Dong Tunnel has been chosen following detailed risk assessment. In this paper, the specific risks to the project programme, associated with adopting either mechanical excavation in the form of a shielded TBM, or drill and blast excavation methods, are assessed. From the risk assessment results, and taking other important factors into account, such as project sensitivity and local experience, the recommendation is made that the relatively low risk drill-and-blast method is the most appropriate for construction of Young Dong Tunnel.

영동터널의 굴착공법은 다음과 같은 세밀한 위험도 분석기법을 통하여 결정되었다. 본 논문에서는 실드 TBM과 같은 형태의 기계화 굴착공법과 천공 및 발파에 의한 굴착공법에 따른 공사중 특정의 위험도를 분석하였다. 공사 민감도 및 현장 경험등의 기타 중요 인자를 고려한 위험도 분석결과에 따른 본 현장여건을 고려하면 천공 및 발파공법이 영동선 터너라의 굴착공법으로 가장 적합하다고 제안 되었다.
