화원의 높이 및 화재크기별 터널 천장온도 측정 실험

초록

The “Ondong tunnel” is not used now where is one of the tunnels in the Janghang line which is from Cheonan to Iksan. The length of the tunnel is 214 m. The location of the fire source is center of the tunnel and the pool fire with heptane isfor the fire source. Tests are carried out for the various fire sizes, the height and obstructed/open condition of the fire source. Temperature on the top of the tunnel is measured. Even if the fire size is same, the maximum temperature on the ceiling ofthe tunnel for the elevated fire source is very larger than the maximum for the ground fire source. As the fire size is lagerthe maximum temperature on the ceiling is higher. These test results can be very useful for design and guidelines of firedetectors in tunnels.
