Evaluation of Lining Damage Caused by Fire in Tunnels
For the sake of the quick judgment to the accurate lining damage degree and the research of its relationship to temperature scales and ablation times, residual compressive strength coefficient, burning rate of lining cross section and intact rate of lining cross section were firstly selected to be evaluative indexes. And then the damage degree of the lining was divided into 5 grades, that is, the higher the grade is, the more severe the lining damage is. The weight of the factors that affect damage degree of the lining concrete is calculated by AHP and the results’ accordance is tested to be good. Furthermore, the damage degree of the lining under several burning temperature scales and different burning times is obtained by grey comprehensive evaluation. The answer in this paper is accordance with that of paper 3, but it is more scientific and accurate.
