Abstract

Recent study about near-surface is proposed to overcome non-economic of underground railway and to reduce people's complaints of ground elevated railway. In this report, precast modular structure system replacing temporary facilities is applied to ensure the construction ability and economic feasibility. To verify the performance of connection joint between permanent structural wall and upper slab, loading test is carried out. As a result of the test, wall replacing temporary structure to slab connection is possible to transfer bending moment. By 30% increase of bending resistant performance for connection joint using coupler, coupler connection joint is more advantageous to resist bending moment compared to channel connection.

최근 저심도의 도시철도 시스템이 제안되어 지상고가 형식의 민원과 지하경전철 형식의 비경제성을 극복하기 위한 연구가 진행중이다. 본 연구에서는 저심도 지하구조물의 경제성과 시공성 확보를 위하여 가시설을 대체하는 프리캐스트 형식의 모듈식 구조체를 적용하기 위하여 영구 강성벽체와 상부 슬래브간 연결부 조인트에 대한 구조적 성능을 검증하고자 실내 재하실험을 수행하였다. 성능재하 실험결과, 가시설 대체 강성벽체와 상부 슬래브간 연결부 구조는 휨모멘트 전달구조임을 확인하였다. 특히 휨 지배를 받는 상부에서는 채널형태보다는 커플러 조합이 휨 저항 성능이 30%정도 증가하여 유리함을 확인하였으나, 성능 개선이 필요한 것으로 확인되었다.
