Abstract

This paper is a follow-up to previous papers entitled, "Development of Tunnel-Environment Monitoring System and Its Installation" I [1] and II [2]. The target tunnel of these studies is the Solan Tunnel, which is a loop-type, single-track, 16.7-km-long tunnel located in mountainous terrain and passing through the Baekdudaegan mountain range. It is an ordinary railway tunnel designed for both freight and passenger trains. We analyzed the environmental conditions of the tunnel using temperature and humidity data recorded over approximately one year. The data were recorded using the Tunnel Rough Environment Measuring System (TREMS), which measures environmental data in subway and high-speed train tunnels and is installed in three locations inside the tunnel. Previous studies analyzed environmental conditions inside tunnels located in or near a city, whereas the tunnel in this study is located in a mountainous area. The tunnel conditions were compared with those measured outside the tunnel for each month. Hourly changes during summer and winter periods were also analyzed, and the environmental conditions at different locations inside the tunnel were compared. The results are widely applicable in studies on the thermal environment and air quality of tunnels, as well as for computer analysis of tunnel airflow such as tunnel ventilation and fire simulations.

본 논문은 터널 환경 측정 시스템 개발 및 측정 I [1], II [2]의 후속논문이다. 본 연구의 대상이 되는 터널인 솔안터널은 백두대간을 관통하는 연장 16.7 km의 루프식 단선 터널로 산악지형에 위치하며 화물열차와 승객열차가 혼용인 일반철도 터널이다. 본 논문에서는 솔안터널의 환경 측정을 위하여 터널 내부에 3개의 위치에 설치된 환경 측정 장치에서 약 1년간 측정된 온도 및 습도를 분석하였다. 선행의 연구에서는 도심지 및 도심지 인근에 위치한 터널 내부에서 측정 결과 결과에 대하여 분석하였지만, 본 논문에서는 산악지형에 위치한 터널 내부에서 측정한 온도 및 습도 등을 외부에서의 기상 측정 결과와 비교한 것으로 선행 연구와 차별성을 지닌다. 솔안터널 내부에 측정된 온도 및 습도를 월별로 지역에서의 기상 측정 결과와 비교하였으며, 여름과 겨울을 대표하는 대표적인 일자에 대해서 철도터널에서의 시간별 온도 및 습도의 변화도 분석하였다. 또한 터널 내 측정 위치에 따른 환경 특성도 분석하였다. 본 연구에서 제시한 철도터널의 환경측정 분석 결과는 터널의 환기 및 화재 시뮬레이션 등 터널의 기류의 컴퓨터 해석 및 터널의 공기질 및 온열환경과 관련된 연구에 폭넓게 사용될 수 있다.
