지하구조물(지하차도, 지하통로)건설 현황 및 관련 신기술 개발동향 연구
A study on the state of the art on the construction and the new technology of the underground structure(underpass, underground passageways)
초록
최근 지하공간개발이 활발해지면서 이의 체계적인 활용에 대한 연구가 필요하게 되었다. 본고에서는 지하공간 중 지하차도 및 지하통로를 대상으로 하여 국내건설 및 유지관리현황, 지하차도 및 지하통로 설계기준, 설계 검토내용 및 시공절차, 대상 지하구조물의 주요하자 원인 및 보수보강 방법, 이와 관련한 국내 신기술 신공법 현황, 그리고 장래 계획 등에 대해 조사 연구하였다. 현재 64
This study was performed to investigate how to design, where to construct, why to degrade, what plan to use systematically the underground structures such as underpass, underground passageways. About 50% of the underground structures are located on Seoul, Kyungi-Do. In design of the underground structures such as underpass, underground passageways, the required conditions are defined. And also in construction stage, the conditions of soil, required structure depth, site characteristics, reasonable construction method, are investigated. In the selection of details for underground structure, the items mainly considered, are the wall and column type, the sidewalk type, anchoring-system type, the water-proofing method, entranc shape. The reason and the adequate measures for the degradation of concrete structure are also investigated. The initial cracking properties due to the thermal characteristic are considered. The state of the art report on the new technologies are reviewed. The recent project for the systematically application to the underground structures is reviewed.
