Abstract

Various tunnels such as road, subway, and railway are under construction and operation. Various types of linings are used for structural stability of tunnel structures, and concrete segment linings are mainly installed in TBM tunnel construction. In this paper, when a fire occurs in a tunnel, the impact on the concrete segment lining, which is the structure in the tunnel, and related standards, fire resistance evaluation and fire resistance method are investigated through literature review and related contents are presented. Through this, it is intended to provide an information for practitioners to secure the safety of concrete segment linings against tunnel fires.

도로, 지하철, 철도 등의 다양한 터널이 건설 및 운행 중에 있다. 터널구조물의 구조적 안정을 위해 다양한 형태의 라이닝이 이용되고 있으며 특히 TBM터널 공사에서는 콘크리트 세그먼트 라이닝이 주로 설치되고 있다. 본 논문에서는 터널 내 화재가 발생할 시 터널내 구조물인 콘크리트 세그먼트 라이닝에 미치는 영향 및 관련기준, 내화성 평가 및 내화방법에 대해서 문헌조사를 통해 조사하고 관련내용을 제시하였다. 이를 통해 실무자가 터널화재에 대한 콘크리트 세그먼트 라이닝의 안전을 확보하는데 정보를 제공하고자 하였다.
