초록

본 논문은 지하철 터널 유지관리 계측센서의 총 손망실율을 산정하기 위해 국내와 국외의 지하철 터널구조물에 설치되어 운영 중에 있는 유지관리 계측센서의 손망실 현황을 조사하고 분석을 실시하였다. 지하철 터널 유지관리 계측센서 설치 후 5~6년 경과된 시점을 기준하여 총 손망실율은 서울지하철5,6,7호선에서 14.2%, 서울지하철9호선1단계구간에서 14.8%, 영국의 Channel tunnel에서 13.9%로 모두 15%에 근접하게 나타났다. 따라서 지하철 터널 유지관리 계측센서의 총 손망실율은 잠정적으로 15%로 설정하여 설계에 반영하는 것이 타당한 것으로 판단되며, 향후 장기간의 경과년수에 따른 계측항목별 손망실율 연구가 필요할 것으로 판단된다.

In this study, the total loss and damage ratio of maintenance monitoring which is installed and operated in the domestic and foreign tunnel structure is researched and analyzed for estimating the loss and damage ratio of maintenance monitoring sensor of subway tunnel. The total loss and damage ratio at the elapsed time of 5-6 years after installation is 14.2% in the Seoul metro line no.5,6 and 7, 14.8% in the section 1 of the Seoul metro line no.9, 13.9% in the Channel tunnel of England and all of them are close to 15%. Therefore, it is reasonable to reflect that the total loss and damage ratio of maintenance monitoring sensor of subway tunnel is estimated provisionally 15% on design, and hence the study of the loss and damage ratio with the number of elapsed years in long-term by the measurement category will be needed.
