The fire load of a tunnel fire event may have an huge heat release rate of over 100 MW. The tunnel lining may be damaged by the fire because the distance between the tunnel lining and fire is close. A lot of different damage that may occur to a tunnel lining structure during fire. Therefore, this study is desired to improve the fire-resistance of tunnel lining applying a water spray cooling system in order to protect it. The real scale fire test were performed. Experimental results, the ceiling of the tested specimen with an installed cooling system was observed no damage such as breakage or crack. And, after activated system the maximum temperature of the specimen was not reach The ceiling of the tested specimen without an installed cooling system was observed that the temperature was raised rapidly. After approximately 216 secends the flame was spread and the ceiling was damaged. |
