Abstract

Purpose: In this paper, the loss and damage ratio of sensors measuring subway tunnels in a few sections of subway lines 5 and 9 where floodings occurred was analyzed for two elapsed years. Method: The net loss and damage ratio during the two years from the flooding date was 13.4%, which was a gap between 48.9% and 35.5%. The result obtained in the loss ratio of subway lines 5,6,7,9, which were 14.2% and 14.8% respectively, and this can be considered to be a reasonable result since it is similar to the data shown above. Result: Additionally, it seems necessary to conduct further analysis of case and waterproof testing of monitoring sensors, connections between sensors and cables. Conclusion: The loss and damage ratio was 35.5% for 10 days to 30 days and 48.9% for 2 years.

본 논문은 침수사고가 발생된 지하철 5호선과 9호선 일부구간의 침수 전후와 2년 경과기간 동안의 지하철터널 계측센서의 손망실율을 분석하였다. 연구방법: 계측센서 침수일 부터 2년 경과연수 동안의 순 손망실율은 48.9%에서 35.5%를 빼면 13.4%로 지하철 5, 6, 7, 9호선의 손망실율 14.2%에서 14.8%와 경과연수는 차이가 있지만 유사한 값을 보여 합리적인 손망실율로 판단된다. 연구결과: 향후 추가적인 사례조사 분석과 계측센서 및 센서와 케이블의 연결부에 대한 방수시험 등을 통한 연구가 필요할 것으로 판단된다. 결론: 침수 기간 10일에서 30일간의 손망실율은 35.5%, 침수 2년 동안은 48.9%로 나타났다.
