Fire-resistant Performance of Concrete Flue Slabs in Tunnel
2012
The fire-resistant performance of the concrete flue slabs used in Yangtze river-crossing tunnel in Shanghai is studied in terms of tunnel structure design,flue slab fire-resistance design,concrete mixing proportion and concrete fire-resistant performance assessment,so as to guarantee the safety of the tunnel in case of fire.The fire-resistant performance of the concrete flue slabs is assessed by means of fire-resistance test.The test results show that the concrete flue slabs are good in fire-resistant performance,which can improve the safety of the tunnel in case of fire.
