Abstract

Recently, it has been made many adjacent construction of inter-facility by the expansion of urban infrastructure facilities using the underground space. The complaints relating to the stability of the facility by adjacent construction is common. In this study, it was conducted for the subway line 5 Gimpo airport station structure in the upper Gimpo urban railway to determine the behavior characteristics of station structure according to adjacent construction. It was performed evaluation of the safety zone and excavation method for station structure. And after a review of damage evaluation, track irregularities and structural calculation by using a numerical analysis, stability of the station structure according to adjacent construction was evaluated to be secured. This study is expected to be used as basic data in advance if you need to review the effects of nearby structure according to adjacent construction.

최근 지하공간을 활용한 도시의 기반시설 확충으로 인하여 시설물 상호 간의 근접시공이 많이 이루어지고 있으며, 근접시공으로 인한 시설물의 안정성과 관련된 민원이 빈번하게 발생하고 있는 실정이다. 본 연구에서는 근접시공으로 인한 정거장구조물의 거동특성을 파악하기 위해 김포도시철도 터널이 계획된 노선 상부의 지하철 5호선 김포공항역 정거장구조물을 대상으로 연구를 수행하였다. 정거장구조물의 안전영역 평가 및 굴착방법에 대한 개략적인 검토와 수치해석을 통한 상세검토를 수행하였으며, 손상도 평가, 궤도틀림 및 구조검토 결과 근접시공에 따른 정거장구조물의 안정성은 확보되는 것으로 평가되었다. 본 연구는 근접시공시 인접구조물에 미치는 영향을 사전에 검토하는 경우 기초자료로 활용될 수 있을 것으로 기대된다.
