Abstract

Purpose: The objective of this study was to improve smart monitoring and monitoring management technology in long tunnels by investigating and analyzing the normal operation rates of monitoring hardware in the long tunnels of high-speed and urban railways. Method: This study evaluated, analyzed, and compared the normal operation rate of 6-8 types of monitoring hardware for each long tunnel, targeting three high-speed railway lines with a long tunnel (i.e., Suseo-Pyeongtaek Line, Gyeongbu Line, and Honam Line) and two urban railway groups with a long tunnel (i.e., Seoul Metro Lines 5, 6, and 7, and 9). Result: The rank of the normal operation rate of monitoring hardware was in the order of Suseo-Pyeongtaek High-Speed Railway (92.1%), Seoul Metro Lines 5, 6, and 7 (85.8%), Seoul Metro Line 9 (85.2%), Gyeongbu High-speed Railway (80.5%), and Honam High-speed Railway (46.7%). Conclusion: The mean normal operation rate of the monitoring hardware in the three high-speed railway long tunnels was 83.4%, and that of the two urban railway long tunnels was 85.5%, indicating that the deviation between them was small. The mean normal operation rate of the monitoring hardware in the long tunnels of the five high-speed and urban railway lines was 84.2%.

연구목적: 본 연구는 고속철도와 도시철도 장대터널 계측기기의 정상 작동율 현황을 조사하고 분석하여 장대터널에서 스마트계측과 계측관리 기술을 향상시키고자 한다. 연구방법: 고속철도 장대터널 3개 노선인 수서평택선, 경부선, 호남선과 도시철도 장대터널 2개 노선인 서울도시철도 5,6,7호선과 9호선을 대상으로 장대터널별 6∼8종류의 계측기기에 대하여 정상 작동율을 조사하고 분석하여 상호 비교를 실시한다. 연구결과: 계측기기의 정상 작동이 높은 순서는 수서평택고속철도 92.1%, 서울도시철도 5,6,7호선 85.8%, 서울도시철도 9호선 85.2%, 경부고속철도 80.5%, 호남고속철도 46.7%로 나타났다. 결론: 3개 고속철도 장대터널 계측기기의 정상 작동율 평균은 83.4%이며, 2개 도시철도 장대터널 평균은 85.5%를 보여 편차는 크지 않는 것으로 나타났으며, 고속철도와 도시철도 5개 노선의 장대터널 계측기기의 정상 작동율 평균은 84.2%를 보였다.
