Abstract

This study analyzed behavior of the segment lining considering connection type between inner-slab and segment lining for a double deck tunnel by Shield TBM. In order to establish the design requirements of inner-slab and segment lining in double deck tunnel, inner structure of double deck tunnel at each purpose was analyzed and compared connection type between inner-slab and segment lining. And analyses have been carried out through the beam-spring model by MIDAS Civil 2012. As a result of this study, inner-slab, connection type of between inner-slab and segment lining and Lateral earth pressure coefficients were analyzed to verify the significant design factors.

본 연구에서는 쉴드 TBM에 의한 대심도 복층터널의 계획 시 세그먼트 라이닝의 거동을 주요 구조물인 내부 슬래브의 연결구조 형식에 따라 검토하였다. 복층터널의 내부슬래브와 세그먼트 라이닝 설계 요구조건을 정립하기 위하여 용도에 따라 내부 구조물의 형식을 정의하고, 터널 라이닝과 내부 슬래브의 연결구조를 비교하였다. 그리고 MIDAS Civil 2012 프로그램으로 빔-스프링 모델을 이용하여 수치해석을 수행하였다. 본 연구결과 중간슬래브 및 하부슬래브, 내부슬래브와 세그먼트 라이닝의 연결 형식 그리고 측압계수들은 복층터널 계획시 주요 설계사항임을 확인하였다.
