초록
지속적인 터널 건설의 증가는 터널 내 대기질 관리에 대한 필요성을 점증시키고 있어 측정 및 모델 모사를 통한 터널 내 대기질 거동에 대한 연구를 수행하였다. 남산1호 터널 입구와 출구의 $CO2 농도차는 250 ppm~400 ppm으로 출구쪽이 높았으며 환기를 안 하는 차량 내부의 농도는 외부에 비해 200 ppm~300 ppm 낮게 측정되었다. 교통량이 적을 시 터널 내 유속은 빨라지며 일정한 농도 구배를 나타내고, 교통량이 증가하면 일정치 않은 농도 구배를 나타내는 것으로 나타났다.
Abstract
The need for management of tunnel air quality is imminent considering the rapid increase of number and span of tunnels in Korea. To investigate spatial distribution of $CO2 within tunnels, $CO2 were measured and model simulations were performed in Namsan 1 tunnel. Results show that $CO2 concentrations were 250 ppm to 400 ppm higher in the exit than tunnel entrance. Also, $CO2 concentrations were 200 ppm to 300 ppm lower inside no ventilating vehicle than in the tunnel. Both experimental and model simulation results show that spatial distribution and concentration gradient of air pollutant inside tunnel are highly dependent on traffic density.
